I agree. We can't help what we feel, but we can help what we do. I don't consider people bad for thinking bad thoughts. I don't mind that people look at me (I'm very much overweight) and think that I must be be unhappy with my looks or that I lack willpower or whatever. As long as they treat me decently, I still consider them good people.

We can't completely control what we think and honestly, I don't think we should restrict our thinking too much. It can't be healthy.
