Angus Thermopyle (one of my favorites too) was Chaotic Evil at the begining, about as strong a case as you see, however he changed to CG with neutral tendencies by the end.
How could you think he wasn't would he have to kidnap and rape someone to show you otherwise. Oh wait, he did that. Would he have to use medical technology to take over someones mind almost for the espress purpose of torturing them. No, he did that too. How about capturing a whole shipload of people and selling then to aliens who he knwo would use them for bizzarre and torturous experaments. No, wait he did that. I'd hate to encounter what you consider EVIL.
