I would argue that his Charisma and Wisdom would be drained/damaged permanently, since those abilities are associated with self-awareness and self-control.
Quote:
"Post-operative blunting of the personality, apathy, and irresponsibility are the rule rather than the exception. Other side effects include distractibility, childishness, facetiousness, lack of tact or discipline, and post operative incontinence.”
I would play his personality up using this as a guideline. Honestly, this is such a strange way to take a character, I can't really say for sure.
Also, be aware that there are a number of spells that might restore his brain function. So, I'm not sure how well this would work if that's the only thing keeping your evil nature in check...
