If I had a nickel for every time Brad Dourif played a sociopathic space murderer I'd have three nickels. Which isn't a lot but it's still weird it happened thrice.

He is also the voice of Chucky in 90% of the Child's Play franchise.

I really loved his character in Voyager. It was really interesting seeing a psychopath who was aware of his tendencies and knew he shouldn't be around other people.
