Yeah Vedit was much more villian like in the movie then he was in the comic, that was one of the major problems I had with the movie version.I just saw the Watchman and I was very disappointed. It was obvious that Veidt was the villain, from almost the beginning, so much so that I was sure there would be some kind of twist. Rorschach was the only character I really liked, but I thought his voice was terrible because it just screamed Dark Night.
I don't understand why John killed Rorschach, John should have just killed Veidt, i'm sure Rorschach would have stayed quiet about it if Veidt payed the price.
Rorschach made it clear that he believed people had a right to know the truth, and once he returned he was going to expose what was really going on. Killing Veidt wouldn't of changed his mind.
