I personally think that Satan's positioning is extremely exaggerated. We -people- feel better when we have someone to blame and throw all 0ur mistakes and wrong decisions upon him. The beauty is that other people will even listen, agree, and sometimes support and say: "El Sheetan Shater" (Satan is Clever). I actually think that till Judgement Day, "Satan" is lucky (El Sheetan Mahzoz). His job description is soo much matching with his targets, his clients, his working environment, and he can now just score by inertia!
People are weak, and they deny that the real devil is within them, the real devil is their inability to have a serious stop with themselves, admit what they did wrong, ask God & people for forgiveness, and start over. "Satan" is just a CATALYST in a chemical reaction. If you don't put the right ingredients from the beginning, don't blame the catalyst for the results.
I am not defending Satan of course, but I am -again- saying that his role is exaggerated specially with all the knowledge we gain over the millenniums. We should use the power of mind and faith to put him in the real size he deserves.
May God Bless us all from Satan, and from our inner devils.
