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?
Assuming you’re a male, your brains not even fully developed for another 4 years or so. We are all a bit different and you were seeking negative attention without even knowing it, possibly.
Best you can do is acknowledge what you’ve done to yourself, improve and move forward in life.
