How do the Commies treat their 'useful idiots' after they've come to power? Since Satan hates the very image of God borne even by criminals, he even hates--and is actively destroying--those who serve him. 'A murderer from the beginning,' "He comes only 'to steal, kill and destroy.'

I mean, he's prob the one that convinced them to do criminal stuff..

I imagine he is nice to everyone. Again, the devil took Him to a very high mountain and showed Him all the kingdoms of the world and their glory. “All this I will give You,” he said, “if You will fall down and worship me.” -Matthew 4:8-9

Being nice to criminals is not the same thing as being good to them.

if Satan is... lol

He's a lousy master. Uses people up and spits them out, from what I see.

Remember he's the most important angel.. How bad can an angel be? I like the Supernatural interpretation, they tried not to make him too different to the other angels after all.

Depends how you define “nice”

If satan is the bad guy shouldn't he have murdered more people than god in the bible? This is going to bring a lot of apologism from warmonger christians who think mass murder is the solution to every problem just like their god does.
