I have too, and spiders, but i increasingly go to great efforts not to kill them and yet I just killed a fly with no thought at all (it was divebombing me) and then thought about it. How come spiders get such a good rap? yes I know they do good stuff and flies spreaD HORRIBLE diseases and are annoying, but hey, we don't distinguish between people that way, not unless they're axe murderers anyway - if life is a sacred principle we try not to break, why do we distinguish on usefulness/annoyingness?
