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 means you were a bad person, most kids are, that’s why we train them. You choose if you’re a bad person today. I would suggest apologizing to those you wronged in ways that still affect them (prolonged bullying, stealing that significantly ruined a business, hitting that caused long term physical or emotional damage etc). An apology is more than just words, and it won’t always make you feel better. This self reflection is good and healthy.
