List I would not do

I do not have anything on a list if things I would not do. I would do anything as long as there is a good reason for doing it. If I was in a situation in which I feel threatened I would kill somebody, it's called self-defence. Is no reason for me to back out of something just because of being afraid. It sounds it sounds crazy and a lot of people don't believe me but, with any good reason, I believe myself that's all that matters.
