The thing is that Christians will see Satan as not the punisher of evildoers in Hell, but he is the bad guy who is constantly trying to get God's children to turn against him so that he will have plenty of company in Hell after the end of the world when he is forced to spend eternity there. The point where this falls apart is thinking that somehow Satan turns people away from God, and so makes God punish people for eternity even though he really doesn't want to because he loves them. So I don't know if this makes Satan more powerful than God because for some reason God can't change the system he set up where he sends unbelievers and evildoers to Hell to be tortured for eternity.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
