I'm sure I will look really bad, but please answer anyway?

I'm not sure how well I can answer your question, but I'll try anyways. I think often it's the case that the nice innocent one is the one that's made out to be the bad guy. This is probably because the people that are actually bad are the ones that will shift the blame, and lie so that others believe them. where as the innocent one just tells mainly the truth and is less likely to try and twist things to get there way. So if you're made out to be the bad guy, then it's probably due to people inability to believe what others say if they heard something else first from someone they know.

Note: When I say bad guy and innocent one I'm saying it metaphorically, don't take it literally.
