1. Why are Hopper and Murray suddenly John Wick?
Hopper, this one you just gotta accept as him being desperate and having police training. It's not realistic, but it is what it is.
7. Why would 001 claim he planned for his father to take the blame for his murders if he was only saved because of hearing a song he liked?
He wasn't saved because of hearing a song he liked - 001 said he bit off more than he could chew, so when Viktor escaped, it was because 001 wasn't able to continue (He collapses during the "flashback"). The song thing was a theory the kids had, but I think it's a red herring. Especially since the song alone didn't save Max - it just gives them a thing in the real world to sort of let them realize they're in a trance. This carries over into how Nancy and co could hear Dustin and them while in the upside down.
Small correction on one and an addendum on two, Hopper is a Vietnam war veteran, and this season confirmed he was in the Chemical Corps. He would've likely had more combat training than your average police officer. As for the second, I think this is overcomplicating things a bit. When the people are in a trance, they're stuck in a metaphysical headspace. What they're experiencing and the events that happen isn't actually "real", it's more of a mental representation. I don't think Vecna actually fully understood the reason why his dad broke free, but Creel latching onto the subconscious effect of music basically meant his mind overpowered Vecna's influence.
Vecna intending to pin the murders on his dad didn't actually require for his dad to stay alive either. It could've been framed as a murder suicide.
