I'm not into cancel culture as I feel that's a toxic thing in of itself. Though, I do feel disappointment and do believe that sometimes they deserve to be called out a little on their behavior. And be given the chance to learn. On that note, I understand that sometimes people are idiots and do hope they learn from it. If they don't ever do it again, I take that as a sign that maybe they figured it out.
But that's more for the not-too-horrible things. Heavy things like abuse, etc. are a whole different story but I haven't really run into that with any of my biases, so...
I mean, I guess it's dependant on the circumstances and what they did.
