This is certainly true for me:
There are so many people who feel, on a deep and gut level, that they are bad. These generally are not the people who are ‘bad’ in the sense of lacking empathy for others, or deriving benefit from harming others. Instead, most people whose thoughts are tied up in ‘feeling like a bad person’ are acutely tuned in to other people’s feelings, feel terrible when others suffer, and do not behave in ways that are any worse than the average human. In fact, when they describe their core sense of badness, it’s not about actually doing bad things (although bad behaviors do make them feel worse). They talk about how this sense of badness just is. It is their most basic and familiar experience of themselves. Perhaps this is also true for you.
