Being a good or bad person is a judgment call based on an individual's self esteem and perception of self and others. So, you may believe you are a bad person because you have a mental illness and I may not believe you are a bad person because you have a mental illness. Who is right? I judge other people good/bad but I think my judgment can only be an opinion, not a "fact" because I am not that person I am judging.

I believe what I want to believe. I want to be a good person so I do my best to act like I believe a good person acts. If I make a mistake, that does not make me a bad person, one incident does not change my nature or what it is I am trying for. If other people tell me I can/cannot do something am/am not "good", etc., that's their opinion and I may consider it (if I know and trust them and would like their opinion) but I have my own life and agenda and what I'm doing and since I'm the only one living in here. . .
