Scar got voted the second most evil Villains in the history of Disney. Why?

Inspired by Hitler, the most evil person of all history.
Voiced by Jeremy Irons, truly one of the most known and best voices of all time.
He killed Mufasa, making the saddest moment in Disney history and making his own nephew to believe that was his fault.
He has done something more brutal than any other magic powered villain has done EVER. He destroyed almost the entire Africa.
How can someone beat this guy?
There you go, the reference are on the top link, the top tens dot com.

I guess we're pretty much living on the very top spot on everything related to animation.
