Read Flyboys. The Japanese soldiers, especially the officers were acting in a way that could truly be described as evil. One jaw dropping story involved an officer raping a woman, killing her, and then adding her to a stew that was fed to his soldiers. Another mind blowing tid bit was about a Japanese commanding officer that dug up buried American airmen that had been decapitated so he could eat their livers.

While you're at it read "With the Old Breed" by EB Sledge. The Marines in the pacific had the joy of living in the mud next to their own excrement and the magot infested corpses of their best buddies for months at a time so that they could stop the kinds of atrocracies described in Flyboys.
