ppl may not like this, but here's my view on problematic ocs
diversity ftw, ig. everyone has a flaw, something that they're not proud of.
they're okay if they aren't promoting it. they're okay if they regret it. they're okay if it isn't their whole personality. they aren't okay when they're obviously supposed to be supporting it.
i have a few abuser ocs. that doesn't mean that i'm romanticizing or promoting abuse, it means i am making my characters' flaws more diverse.
