can i still work in psychology?

this probably a very silly post, but i still feel like i need to ask. so i find psychology really interesting and i like finding out how people work inside of their heads; it's just really fascinates me. recently though, i've stumbled across a lot of posts about how people's bullies (present or past) for some reason often choose career paths within psychology and therapy, education and healthcare. now, this brings me back to how in the past i had this friend i was mean to when i was around 9-11 years old (i'm 16 now). i didn't BULLY her, but i was not nice to her either and wrote some really dumb things about her in my diary. at the time i wasn't entirely at good mental health either, but that didn't excuse my attention seeking and victim mentality. since it's been a while this happened i don't know how much i remember wrong or exaggerate, either, so memories aren't a reliable scource either which feels unsafe. i really despise this version of myself and how i used to be, but i feel like because i don't have a clear moral slate i don't deserve to work within psychology, and especially within therapy as i'm scared i might not be the best with patients. the concept of controlling and/or manipulative people seeking out professions among vulnerable people, like in therapy, because they like the power and control worries me a lot, because what if the reason what if that's why i'm interested in psychology? i like to try and help people with their problems, but what if it's solely because it validates my ego and i like the sense of control or something??? i'm super scared of lacking empathy and secretly being controlling and malicious, so now i'm wondering if my past traits and mindsets (some of which still exist and i want to work on), and especially my wrongdoings, make me too bad to work in psychology,and if i should consider another path. ik this probably sounds dumb, but i don't know what to think anymore and i want to be on the safe side; i don't want to take the risk of putting myself in a line of work where i can accidentally cause harm or do something bad.
