I would think defending yourself or others would be seen as the same as stopping someone from abusing you. If at all possible one would try to defend themself without taking the others life yet usually when someone is out to kill you asking nicely won't stop it and sometimes you have to kill them to stop it. I agree there is death going on all over the place, plants, trees, animals and even humans so it is a natural part of this existance, yet allowing someone to kill you is not love for you or them. If you believe in the power of visualization and intention then how about visualizing all at peace with one another. That there is no need for anyone to kill anyone...that everyone is at peace with one another.
