Well....you (and most all of us) do "kill" everyday! If you are using antibiotics, antibacterial handwash, even bleach, etc......millions of innocent little bacteria are being wiped out. Just because you can't hear them screaming, doesn't mean they are not dying.
And....the mear fact that you eat animal and/or vegetable matter, means that you are secondarily responsible for the death of some other living thing!
You have already fulfilled your wish.
By the way, I heard that the obumbler told one of his buddys that Shiites taste like sh.t., but Sunnis taste like chicken.
