Because you probably read excerpts from his book where he said his wife divorced him and told him he was so unattractive he turned her off. He said he wanted to kill his ex wife. He needs to be put out of his misery. He needs to euthanase himself. He turns all women off so he is getting his filthy jollies killing Terri and talking about it endlessly, I would not be at all surprised to find him naked at that hospice next to a recently starved to death woman.
Well,
She was just stating the obvious (that he was unattractive). Any guy who gets off on watching someone die is definately not someone you want to be around.
