If I see somebody getting robbed on the street and, in order to help them, I confront the attacker, should I be worried ethically (and legally I suppose) about the result of my actions toward the perpetrator?
For example, what if simply telling them off isn't enough and, in order to stop the robbery, I have to use force and that force causes the death of the criminal? (I guess, for example I could push the robber away from the victim and the robber might hit his/her head too hard on the ground, etc.) Should I stop and think about the best way to stop the robbery that would avoid potentially killing the criminal (and thus risk being too late to help or try something ineffective) or should I rush in to help but risk excessive harm to the assailant? Would I be morally responsible for the well-being of the perpetrator?
Thanks so much!
