I’ve done alot of mischievous and unkind things throughout my education time (k-12) I made fun of people, bullied people, stole from people/stores, hit people, kicked people, did things to annoy people, and just overall did stupid shit to cause problems all because it either felt cool or because I thought it was funny. Some of these were things I did because my friends did them, but some were just me being stupid on my own. I am now 21 and recently I have thought about all of this and feel awful about the things I’ve done because I know it has affected people. I wish I could go back and have never done any of it. Is something wrong with me? Am I a bad person?
It sounds like you were a bad kid, but maybe you won’t necessarily be a bad adult given this introspection. Something to bear in mind is that kids’ brains and minds aren’t entirely developed, often causing that kind of bad behavior- maturity is a real thing, and it sounds like you’ve begun developing it.
I think most people have things they regret from childhood and teenage years. I suppose the key is to be self aware and try to live in line with who you want to be as an adult.
