It's Disgaea D2, not Disgaea 2. (Already been said but I had to say it to.)
Anyways, Disgaea is not supposed to be a serious game at all. I dunno why so many people think it's supposed to be serious with its dialogue.
3guys1hammer, various videos of accidents and incidents, drug runners in Mexico decapitated by rival gangs, and a video of a guy being quartered by horses. I think 3guys1hammer was the one that sickened me the most though.
