Even if there is the slightest chance of there being a Satan, then we have to kill it before it reproduces and tortures everyone everyware. It's our duty by God to kill evil. Why are we on the Earth anyway? We are here as part of God's great plan to kill Satan, there is nothing else. Ever seen a baby being tortured by Satan? Well imagine billions of babies per planet, billions of planets per galaxy, billions of galaxy's per universe and finally billions of universe's in a multiverse. If Satan does exist then even more than that would by tortured forever. Just because you feel good now, doesn't mean there is a God. And, just because you feel terrible doesn't mean there is a Satan.
