It's widely believed that Loki hates his brother. All this "no matter how much he said he hates Thor." - it is everywhere in the fandom. But the fact is that he NEVER said it. This is an interesting theory.
I agree wholeheartedly that Loki is infinitely better than Odin. This scene proves Loki loved a mortal once or even still does. Look at his face as he speaks. He is trying to save his brother from the heartbreak.
