There is no bad guy in my equation. I tend to think that people are generally good. If they are purposefully hurting others, maybe it is due to MI, or maybe it's due to insecurity, or maybe it's their response because of something that happened to them, or maybe it's something else entirely. But I think that a lot of times, people who hurt others do so unintentionally - they are focused on themselves and what they want and that trumps whatever ability they have to put themselves in the other person's shoes or see the ripple effect that their actions have on other people.

That being said, I don't think that any of those reasons are an excuse to treat someone badly. They are possible explanations but by no means to be used as justification for wrong actions.
