I don’t see being nice as something to be regretted. There are times when being mean in response to mistreatment is justified but I would rather put a stop to it without having to resort to that if possible. Don’t let the actions of bad people turn you into a worse person.

I find it hard to be mean even when I feel it. A lot of it is fear of it being unjustified but I just don’t really think that it works most of the time. When I’m mean to somebody it plays in my mind for days giving them undeserved time in my brain but when I just become neutral and refuse to engage with them I’m generally more at peace with myself after and the event no longer occupies my thoughts, they aren’t worth the effort.
