Because kids like to like things they aren't "supposed to" and i think he's generally seen as a rebellious thing to like. and the devil has become fairly mainstream in today's culture, so he's seen more as a cool evil guy than the guy that tortures you when you die or whatever christians beleive in ;o
its not god that doesnt do a good job, its SATAN who causes all the bad things. god didnt make eve eat the apple, satan did. and god would forgive lucifer, its lucifers will that hes not an angel!! gah, everyone's butts are starting to become smarter than their beholder.
pffft. the only "kick out of seeing people suffer" would just be satan trying to get to you. if he got a kick out of seeing people suffer, would he die on the cross for us?
Also, God is a dick
