To admit evil exists only to use it as a reason against God's existence must be a truly frightening position. In one quick swoop a person claims something dreadfully awful exists with no context of ultimate good to place it in. What sort of horrendous fear must slowly grow deep within those who affirm evil yet deny God? It is like saying, "There is deadly poison all around me, and that's proof there is no antidote!" At any moment evil can touch you, and what is your antidote? Well you just claimed there isn't one. You better walk lightly on the thin ice of life.
