原文あった

If you really imagine the stakes of him,in his youth,
having all these special powers and having your parents kind of be absent during that process on their own agendas,
[being] equally as selfish.He's lost in the world that he was raised in,
and feels that he was kind of abandoned by the people that he's closest with.
He's angry because of that,I think,and he has a huge grudge on his shoulders.

「捨てられたと感じて、とんでもない恨みを抱えている」とか書かれていたらそう思うけど
感じたことが原因と書かれるとそのあとでも何かあってより恨みを持つようになったとも解釈できると思ったんだが
原文はbecauseなのでそうっぽいな
