My personal issue is that Jason doesnt have a lot of reason to hate superpowers, from a character standpoint. People suddenly having power? I mean, a dude picks up a gun and has the ability to kill any person in room if he places his shots right. In that sense a metahuman is no more ‘powerful’ than a man with a gun. I suggest expanding upon why he hates metas more. I think it will add to his character and make his character arc more impactful.

EDIT: a few words
