I don't think I'm a bad person, but up until my 30s I made a lot of bad decisions that continue to haunt me. Even just small things like one time that my sister wanted to take a picture, but I was in a rush and in a bad mood so I didn't take it.
Ultimately I feel both a) the weight of the consequences of what I've done (the things I ruined, the people I hurt, etc.) - and b) the shame of having these things as part of the story of who I am and what I've done.
