It depends what constitutes as a bad person. If someone is racist. I'll just never buy their stuff. As with most possibilities of someone being "bad" I'll never buy their stuff so they will never get revenue from me. If I like their stuff enough I'll just torrent and be done with it. If it's something that is put under an exception for me then I am not quite sure what I'd do as I haven't been put in that situation yet.

Nope. I can't even to R. Kelly anymore, but that's besides the point.

But I don't support them. Example; I like Blood On The Dancefloor's music but Dahvie is a shitty person. So I listen to his music but like I don't buy the albums lmao.

^^^ I'm not a huge BOTDF fan but that's my view for Ronnie Radke from Falling In Reverse and XXXTentacion. Both are not good people but I'll be damned if they aren't good at what they do. There's a very fine line on what's just too despicable to support at all, but I think some people overreact on what's considered "bad" especially when the act in question was a decade ago.

^^ Ronnie is another good example.

Depends on what they did. If they are simply jerks, then yes. If they have committed atrocities like rape, torture, murder, child abuse, animal abuse, etc., then no.
