I have a fear of turning into a bad person

I don't think I'm the only person that thinks like this but I want to talk about it to see if anyone has the same of thinking, experiences, etc.

i have my fair share of flaws just like everyone else, like, I can be annoying, really weird, lazy, kind of bitchy, very blunt, etc. I do have some redeeming qualities like I'm polite, caring, looking out for others, motivated, etc. And I do try to fix up my flaws and reflect on my actions to move forward and become a better person than like let's say a year or 2 ago. so it's not like I fuck something up and not learn anything from it however, I get scared that I let my flaws take over me or life doesn't work the way I want to and I end up becoming a terrible, degenerate being like my terrible ex-boyfriend, politicians from my country, LOLcows like Novaonline and Chris Chan or people like Jeff Epstein or the pedo from the Blood on the dancefloor band.

It genuinely terrifies me, I do not want to become a terrible being and lose everything, I try to focus on the brighter side of things, but those thoughts follow and I can't completely get rid of them. I'd say the root of my fear is my Ex-boyfriend and those LOLcows, but the one who planted the seed is my ex. he was problematic guy, rude, disrespectful, creepy, and also a bit of a degenerate. I'm aware that his parents had problems and he had some trauma bit obviously it doesn't excuse his actions and how he mentally fucked up the way I looked at love for a long time. It took me years to heal and permanently cut him off from everything because despite everything I was still in some way in contact with him, but I can't deal with his negative vibes and influence no more. Even with that, with everything, I get scared that I would in some way end up like him or any other terrible person, I know I'm not a bad guy, but my mind is fucking with me and telling me that sooner or later I would end up becoming so bad that satan couldn't compete.

So that's all I have to say, I hope someone out there can relate in some way. I wouldn't mind y'all sharing some advice, I'd appreciate it <3
