For the longest time, we've never really understood why Loki acts the way he does. Why he is the way he is. It's easy to forget but this is 2012 Loki, so the change in perspective he undergoes over the next six years hasn't happened yet. He may know what his future would have been, but he doesn't understand the path he walked down.
This is huge because it tells us that Loki from 2012 believed that love only hurts and ultimately isn't real. He didn't believe back then that his family - Thor, Odin and Frigga - truly loved him and so much of what he says is a projection of his true feelings. He thinks freedom is a lie because he doesn't think he ever had any, he thinks love is a lie because he doesn't think anyone ever truly loved him.
Suddenly his obsession with becoming the ruler of something, of anything, makes more sense. It would take him six years to realise that he always had the very things he sought so desperately, but by then it was too late. All the stuff that's happening now is like a second chance for him. A chance to realise that his family does love him and always did and that he has the freedom to choose his own path, make his own mistakes and that he doesn't have to live in anyone's shadow.
