Chaotic/Rebel Good and Lawful/Moral Evil character types are the most entertaining for me. Idk why.
Chaotic Good characters usually do whatever is in the power to do good, they usually aren't held back by some bullstuff code or have restraints on their power. This often makes them being more interesting as a character overall instead of being cookie cutter and dry.
Lawful Evils are like your Walter White and more "moral" evil characters. They do things for somewhat justifiable ideals while the act itself is evil. I find those characters to be outright more interesting than any character out there. It takes a lot to play a Lawful Evil role.
