Theoretically I've believed that there is no inherently good or bad person. So I used to tell people, don't tell me this one is good or bad, I don't see people in that dichotomy. I even went that far that we are all good in essence. Just to realise that I still believe I am not. And this was shocking to realise.
There is a big contrast between the theories I claim to believe in and what is really going on inside me.

We who are very susceptible to other people's emotions, sometimes get lost in the mirror they show us. We think we are bad because we are not conforming to values that are not even ours.

Though, it is said that guilt comes from acting against our values and shame is about acting against the values of the community/ group and it is related with believing that we are bad. So if I do something against my values, I should feel guilt, not feel that I am bad. So being bad in this case might really be correlated with not conforming to the values of others. But then there is all this "being bad" feeling that we drag with us from childhood and it is not relevant anymore. There is no community anymore that would kick us out for that which we'd been shamed for as chidren. Still, it's there, poisoning our lives..
