Is it vibes if they’ve already done something shitty and people just ignore it until it happens to them?

I’m still messed up from what a certain someone did to me in high school, and it’s taken her slowly treating the rest of our mutuals the same one by one for each of them to reach the same conclusion that I had back then. Except some of them deciding that they still want her in their life for whatever reason. People seem to have this weird idea that they can manage her or deal with her to prevent her from hurting them.
