Genghis Khan - Crazy Killer?

Killer? Yes. Crazy? Not at all. He was more along the lines of a strategic mastermind. All of his attacks were planned out; they weren't just random attacks on different peoples. In fact, he would often attack an enemy to "psych out", so to speak, nearby peoples. That way, they would instantly surrender and a bloody battle would be avoided. If he really was a "crazy killer", he would just go in and kill everyone. But, like any smart general, he used strategy to plan out his attacks and actually prevent excess bloodshed. Therefore, he should actually be considered a military genius.
