I generally don't kill things either. Not because of the guilty thing, but because I think that one of the reasons we were put here is to be protectors of the environment and the creatures that live here. And most of the time, if something bites, stings or threatens us, it is because they are afraid and are just protecting themselves or their young, or have been startled. I also find all around us to be so fascinating and the design of things simply amazing. Humans try to copy these things and can to a certain extent but never with the same effectiveness as the original natural design.
Any rate, enough rambling...
