I don't believe myself to be good I've never done anything you stated either but I've done other things and I will always mess up...
I felt sad when I read this. Self-esteem is an important part of living a fulfilling life, and all too often I've seen religions beat it out of people with slanderous nonsense like Original Sin or the myth of a perfect, holy god who supposedly can't bear to be in our presence.
There's plenty of room in the universe for good gods
and good mortals.
