Did you feel sorry for Red in the end?

If "she" hit you in your mentally unstable position, you'd eventually end up dying. Thats what I dont understand about the puzzle. When you kill her, Clarence tells you he was messing with your brain.

The trick is, Clarence wasn't messing with you. That really was a tuurngait (sp probably wrong). His trick was to make you think you'd just killed your last hope by making it appear as her body. That's why you can still be killed by it.
