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.
Its important to note that maturity doesnt automatically come with the brain fully developing. The brain being developed is a requirement for maturity though.
