Religion is telling nonsense. It can t handle the everybeing of God and it produces mutants of logic. On one hand, all is God s will, on the other - there exists sin. If all we do was just His will, then every evil we commit would be on his command. God is not good, as he created Satan, or it s not omnipotent, has always been equal to Satan.
Religion can t agree to any of the two options.
It says Satan plays his part God appointed him. That would mean his independence. If luring to evil doesn t create evil in man, just that it activates the evil, which already is inside him - then Satan is not evil. That seems to make some sense, though this version of Satan serves God as well. There you can see that in order to explain presence of evil, religion takes God away from man, allowing Satan to make the intimate approach.
