When you watch your family get butchered and your village burned to the ground as a child, surely it'll come back to haunt you, but as common a plot device as that is in most RPGs it's rare that you actually see the hero make that big of a deal about it. They'll usually have some kind of sad lamentation halfway through the game on a moonlit bridge somewhere, but that serves more to try to get them in the pants of the main heroine than anything else. This has always bugged me. For every game where the protagonists' beloved peasant village is torched in the first ten minutes, I'd always wanted to see the hero spend most of the next twenty hours of gameplay championing the cause of good, only to completely loose it at one point and methodically go door-to-door with a large axe reenacting the horrors of his childhood.
