Moral policing

Hello,

I would like to learn more about my tendency to engage with people who I feel are acting out. For example, in a small social circle if I feel one person is mistreating another I will call them out. In a large social setting such as online, I too call out what I consider poor behaviour/morals. Typically, I don't care what people think about me but I do seem to care about how they behave and think.

Is there a source or a set of keywords would help me learn more about these tendencies of mine?

Thanks
