Sometimes, things are better left unsaid. Sometimes, your imaginations are enough. Sometimes, ignorance really is bliss.
Remember Darth Vader? He used to be the epitome of evil, the most recognizable symbol of scum and villainy in cinematic history. Then you saw the prequels and learned the awful, retconned truth: "Annie" liked to build toy robots, wear pageboy haircuts, yell cutesy catchphrases and hit on his babysitters. The character hasn't been the same since. Unfortunately, this happens just as often in videogames.
