Mainly, sin is a product of the fallen nature,and a rebellious action by the sinner. It is not approved of by God, and is why Jesus came to be the substitute. Ok...but, in certain cases, God uses the sinner for a purpose.Like, at first glance, we look at Judas,and we would think he's the biggest traitor of all time.But ,it was all part of a plan.If Judas DIDN'T turn Jesus in, and Jesus didn't go to the cross, we'd all go to Hell!!And those Roman soldiers, and the Jews who clamored for the crucifixion..sure, they did it with sinful intent,BUT, again, God controls foreordained circumstances, so, even though the devil might have "stirred them up", it was part of "the plan",and again, if they didn't do that, Jesus would have "walked", but...
