what good thing has the devil done?

I believe good thing doesn't come to evil.. all good things come from God, because evil is bad and bring bad things, not good things. The thing is that, sometimes it is hard for human to differentiate what's good and what's bad to them. What really good is seen as something bad, while something bad is seen as something really good. But, for people who trust in God and follow their heart in Him will find the true good things of all.

Welcome to Mylot Anj! The most wonderful thing that the devil has done is that he has proven to everyone and all that he is such a total loser when God Almighty comes around.

The only thing it did good is the fear that it causes in people who believe in him thus giving people who threaten with the devil great power and opportunity for manipulation. I Don`t believe in the devil. I believe there somewhat good and somewhat bad people.
