So the Imperium can just STOP someone from dying? Or was that was because he was a Primarch?
They used a stasis field. It wasn't so much as stopping him from dying as essentially freezing him.
Okay so about the Primarchs and the Horus Heresy....oh boy here we go.
1) Did the Emperor ever actually care about his "sons" other than Horus?
I spent all day listening to various lore videos and read the various wiki entries for the Primarchs at lunch and in between. Every single story was the Primarch being tossed into the shit ass of nowhere and then they save the world. Its awesome. I loved it. Then the Emperor shows up and "tests" them or whatever. In every story the Emperor is shown to have some kind of pride or care in his "son" and what they have accomplished. Yet when the Heresy begins he starts throwing his sons at each other without a second thought. He outright tried to murder Magnus for trying to warn him and sent his brother to do the deed. And once he saw that Magnus was actually right I saw literally nothing to suggest that the Emperor even regretted what he had done to Magnus. So did the Emperor ever actually care? Or was it more about the things he could accomplish with them rather than caring about the Primarchs themselves?
He cares for them as much as you might care for a really nice toolbox you bought yourself or a nice painting you made. You might be proud of it. You might love to use or look at it....
....in the end, though, they're tools or objects to be used by you.
2) Is Magnus The Red the most fucked over character in the series from an objective standpoint? Or have I just not gotten deep enough?
The guy is a devout follower of his "father" and trains his own legion as best he can in order to serve him. He follows every order to the letter (aside from the whole psyker thing) and serves with distinction. He is the only one of the Primarchs to be there when Horus falls to Chaos and desperately tries to stop his brother from becoming a monster. And then when he fails his first instinct is to warn his "father" and the imperium as quickly as possible. And yes in his haste he fucked all kinds of shit up, but he was doing what he thought was right. There was no malice in his actions. He meant no harm. And what happens? His "father" basically calls him a liar and then sends his brother to imprison him and ultimately to try and kill him thanks to Horus and his goons. Then with seemingly no other options he turns to the powers of chaos after feeling betrayed and abandoned. Its just such a SHIT outcome for such a cool and loyal character.
Honestly, there's probably people who have been fucked over more, but Magnus is interesting. There's a section of fandom that loves the "Magnus did nothing Wrong!" meme, similar to the Magneto was Right from X-men.
I also find it hilarious and will meme it with friends, but in all seriousness, he fucked up a bit.
Magnus was (and is) an immensely powerful psyker and the Emperor was probably going to use him as a battery for the Golden Throne (see, another example of Big E viewing them as tools and not sons). That being said, he made mistakes with the Warp. He thought he knew a lot more than he did and didn't really seem to be aware of Chaos or the full risks of the Warp. He thought he did and was arrogant enough to act on that assumption.
So, Magnus did nothing wrong!
....he did.....
But he didn't! :).
3) Why did the Writers immediately decide to get rid of all the coolest characters in the story after the Heresy was over?
I read all about these badass Primarchs, their abilities, creeds, and personalities leading to the Heresy and then.....*POOF*...... they are all fucking gone within a few hundred years it feels like. They either become daemon princes and piss off to the Warp or they just die in the lamest and simple ways. Or even worse a few of them just walk into the Eye of Terror like abunch of lemmings running off a cliff and now they are just "missing". As a writer why in gods name would you spend so much time and so much energy building up these amazing characters, have them grow, have them face all levels of horror and challenges only to have them either die a pointless death or just fuck off to nowhere almost immediately? It makes no sense to me! All of the best Primarchs are now just dead (Sanguinus is the GOAT btw imho) or missing. Leman Russ is coolest one still "alive" and he is nowhere to be seen. Its just so depressing. It feels like wasted material and I hate that in a good story. The story of the Imperium would have been so much better in my opinion had the Primarchs been aroudn for the rebuilding. Or at the very least just one or two of them. Instead we got a bunch of no-namers doing this and that.
The others answered this pretty well, but I'll throw out an additional viewpoint. I like that the super powerful Primarchs are mostly dead or indisposed. Granted, the Daemon Primarchs are still around (Lorgar, Mortarion, Angron, Magnus, Perturabo etc) and Guilliman's back (and the Lion is technically asleep, etc)., but until recently even the Daemon Primarchs were inactive. That let things happen without insanely powerful "demi-gods" interfering.
The Primarchs are a lot of fun and the Horus Heresy series has done very well in utilizing them, but I still want them to be somewhat careful with their usage. Personal opinion, obviously.
Except Perturabo. I kind of like him, let's do more with him.
4) Is the Emperor a moron?
Because the way he is written during the Heresy makes him seem like the biggest idiot in the Imperium. I read countless stories and watched about a dozen videos about the guy biding his time and planning out his every move over the course of millennia only to watch him piss it all away in about 7 years.
- He was blind to the obvious grudges or flaws that some of his "sons" possessed. (Mortarion and Fulgrim come to mind)
- He outright ignored the warning from Magnus about Horus
- He somehow missed the fact that over half the legions he sent to Istvaan to stop Horus were traitors and that led to the Dropsite massacre despite being the most powerful Psychic in all the galaxy
- And then....the dumbest part of all. He allowed a Chaos infused Horus to beat the ever-living shit out of him and literally DISMEMBER HIM before he finally got the clue that his "son" was no longer in that noggin of his. Because somehow him murdering billions of humans, murdering his "brothers", swearing allegiance to the powers of Chaos, and laying siege to Terra were somehow not enough evidence to prove that fact up until then.
And yet this is the guy who was there with humanity from the start. The god of mankind. The leader of humanity. The most powerful and intelligent etc etc etc. It just boggles my mind. That entire section of the story had me just shaking my head. Don't get me wrong I still loved the story overall, but the level of stupidity on the part of the Emperor is just mind-numbing. I just do not understand what happened at all.
Sorry for the rant, but that whole Heresy story was a god damn trip. So many highs with so many lows. It was a rollercoaster of emotion lol
I'll be interested in how the Horus Heresy retells the scene with the Emperor versus Horus and the death of Sanguinius.
It's just another version of a story about hubris. The thing to remember about the Emperor, and this might help with some of the above, is that he can't see the future. He's an immensely powerful psyker, yes, but he doesn't seem to have prognostication powers. He's just very smart and VERY arrogant. As mentioned above, he and Malcador suspected the Heresy might happen, but didn't know all of the details of it (obviously, in retrospect).
That means he has blind spots (Malcador chides him several times about this). He will make mistakes because he is sure he's right.
That and Magnus forced him to mostly have to sit on the Golden Throne when he warned him....otherwise Terra would've been swarmed by daemons. That definitely caused him not to be able to 100% focus on the Heresy. It was mostly Dorn and Malcador handling it.
*****
We've mentioned a lot of books here, but there's an excellent short story I'm going to suggest now because of your focus on the Emperor. It's called The Last Church. There's no battle scenes in it and all it is is a dialogue between the Emperor and the last priest on Earth (catholic ish).
The premise is that the Emperor is wrapping up the Unification of Terra. The last church is there and his army is ready to destroy it because the Emperor's whole thing is The Imperial Truth and secularism. The priest inside is refusing to leave. He goes in to debate the priest and it goes from there.
