IF GOD CREATED ALL THINGS, THEN HE CREATED EVIL.?

THE DEVIL, SATAN, LUCIFER WAS AN ANGEL IN HEAVEN WHO DECIDED TO REBEL ( SO FREE WILL IS NOT JUST FOR US, THE FLESH) GOD CREATED THE ANGELS, HE KNOWS ALL, HE IS THE ALPHA AND THE OMEGA HE KNEW ADAM AND EVE WOULD REBEL. AND THERE HAS BEEN UNTOLD SUFFERING SINCE . WHY DOES HE HAVE TO PROVE ANYTHING TO SATAN WHO HE CREATED IN THE FIRST PLACE? WHY DID GOD CREATE SATAN AND THE MULTITUDE OF ANGELS THAT FOLLOWED HIM. AND IF THERE WAS A WAR IN HEAVEN BETWEEN ANGELS,WHO ARE IN GODS PRESENCE, WHAT THE HELL DID HE EXPECT FROM US LOT DOWN HERE, THE "FLESH" NOT VERY P.C. BY THE WAY.
