There is no battle going on between satan on one side and God on the other. There is no satanic evil force influencing men to commit heinous crimes like the recent slaughter in Syria, the genocides in the Bosnia, Africa and Cambodia and the holocaust itself. As CS Lewis concludes, evil is just the perversion of good and it is generated by plain old human beings who abuse the free will they were given because of greed, power, corruption and just plain old hatred. I sure as hell hope there is some extra terrestrial judge who will hold them all accountable. There sure as hell isn't one on earth.
