Is it weird that I’ve never committed armed robbery and feel afraid to do it?

I might be a bit of a Goodie Two Shoes but I have never done an Armed Robbery because I know that People act unpredictable when under stress and I would feel guilty if I were to hurt or kill someone resisting Me during the act. I know that it would be combat violence and nothing to feel guilty about but my overly moral mind would feel guilty knowing that I started the situation and the resisting person was just acting out of fear and self defense.
