Genghis Khan

Genghis Khan had power over almost anyone he wanted.  I think he was a skilled ruler gone crazy.  He had a rough childhood and lost his wife.  He became a killer and terrorist because of it.  He was crazy and did go overboard, but his intentions were good.  He wanted to find his wife and get her back.  He became overwhelmed and continued killing and capturing people to gain his reputation he has now.  I think he was a good intentioned ruler who just lost control of himself.
