God knows who is wicked and who is not. He knows whose faking it. But of course, he is all-powerful so people naturally to save their own necks will conform or try to impress the deity. So to get past that facade he does like we do, the unannounced "spot check." That's the story of the Good Samaritan. The rabbi and priest walk past this person on the street they don't want to deal with. But little do they know it's the king! Had they known it was the king or recognized him, they would have been sooooo exited for this opportunity to gain his favor, right? They would have bent over backwards. But because he was just a common-looking man, they ignore him. But the Good Samaritan, with truer values, helps this man out. In the end: Suprise! He turns out to be the Messiah, the King! The Good Samaritan gets the kings blessing, and the priest and rabbi who claim to be the king's servants get their walking papers.

So yes, in the end God did trick Satan. Satan was a murderous bitch (called "the woman" at Gen 3:15) from the beginning and the temptation to kill billions of potential innocent humans was just too much to resist. But God turns the tables on him/her by making it possible for those who were killed to be adopted by Christ, who dies without children and thus entitled to adopt, and thus they get saved. That is, their death is not permanent. So in the end, it's not about dying, everybody dies. God makes it a new requirement. It's becoming eligible to come back that makes all the difference.
