Which game villain is the most evil?

[Vern5]

The player in all of the sims games. There they are, innocent little sims, enjoying their idyllic lives of normalcy and peace. Suddenly, one of the family members finds himself entrapped within a box of walls, left to starve to death. Little Suzy tries to exit the pool only to find walls enclosing the entire structure.

Seriously, the player is the ultimate evil in any game. We control the lives of these characters and can even force them to die horribly and reincarnate to do it again so long we select "continue" instead of "go to main menu".

Silent Hill (yes, just the town) Honestly...oy vey.

 

[Atticus89]

Lord Yggdrasil from Tales of Symphonia.

He split a planet into two separate worlds and created a system that lasted for 4000 years that involved the manipulation of the populace to worship a false goddess, the sacrifice of chosen people to revive his sister that was killed, had no problem with sticking humans into concentration camps called "human ranches" to create gems that would give his followers strength, and lost his mind when his sister rejected his plans.

Above all, he's a fallen hero. He saved the world, was a good guy, but lost his faith in life when those he risked all to save killed his sister.
