the worst thing he's done was in his backstory which was over two decades ago and he served his time for it.

as for what he's done while he's been in the show well he decked Ravi and has been a bit of a dick to people but other than that he Honestly isn't really a straight up villain.

he's just the same as everyone else in the cast and not really the lesser of two evils when compared with Suki I'd say their on even footing when it comes to Villainess acts.

given everything she's done in the past so like I said I think he needs to do something big soon otherwise if he does end up getting a comeuppance then its gonna feel unearned since he hasn't actually done much of anything since he's been back.
