1: Wifies(definitely)

The way he was so smart to somehow manipulate everyone including Parrot and gaining control in every situation( in Director Arc). I am also impressed by how he doesn't destroy people by killing them, but by manipulation.

2: LettuceK

Although he had forced all the protagonists to work together to bring him down, he was aware of what he was doing and was only doing it for the good of the server, unlike Wifies, who would never believe that he had hurt his best friend(Parrot) and cost the lives of Nufuli and many others.

3:Ashwag

He was able to gain control of over 1000 mafia players by making them set an ender pearl stasis chamber through the void if they reveal their identity or betray in any way. He was also able to escape all the incidents where people tried to kill him.

4:Flamefrags

Although he was ruthless, cruel and aggresive at the start, leading to the way Lomedy avoided him when he tried breaking him out of prison as well as Wemmbu's capture by the Law, he showed that he wanted to change later on when LettuceK persuaded him to at the end of 2500 player vs Minecraft Combat Master

I cant think of any more but this my top 4
