Yeah, DE. He seems to really fly off the handle at the slightest thing in the EU.

Anakin I could see as having uncontrolled bouts of saber-swinging rage, but I always saw Vader as mostly in control, in a sort of Bruce-Banner-Always-Angry way. I mean, there are obviously things that get Vader's goat, as we saw in Star Wars and Empire, but he always handled them with the Force, which just seems more "mature" to me. I feel like him just slicing poor Captain Needa in half wouldn't have had the same effect as "accepting" his apology in an unconcerned voice as he telepathically strangled him to death.

And, Wook, I always remember that moment from Splinter very vividly. One of the first pieces of EU I read as an impressionable child.
