The thing with Loki is that he's both attractive and relatable.
Spending your life trying to prove yourself to others, trying to get the same respect and yet, no matter what you do, no matter how much you try, it never works. You try doing the same things others do but somehow, you still get treated differently.
You know you have just as much value as others, yet you're not seen and treated as if you do. You bend and stretch and force yourself but nothing works, nothing is enough.
Is it a wonder that we go feral? Is it really surprising that we give up and say "to Hell with it; I'm going my own way!" If you deny us recognition, why would we owe you anything?
I don't want Loki to redeem himself; I don't want him to apologize for his actions or become a bland, boring "hero". I want him to find his own way, regardless of what the supposed "good" people think of him. I want him to realize that he never again has to live up to others' expectations.
I want him to be free.
