In Watchmen, Rorschach (Kovacs) and Nite Owl (Daniel) discover Ozymandias' (Veidt) plan after breaking into his office computer. The password he used was incredibly easy to crack: Rameses II. There was a book of that title on the shelf beside his desk, and he was known to be obsessed with Egyptology, Pharaohs, etc. Even worse, his superhero name - Ozymandias - is the Greek version of the name Rameses II. Considering the fact that he's supposed to be the smartest man on earth, it appears that he wanted his former colleagues to uncover his plans.
After their discovery, Nite Owl and Rorschach head to Veidt's headquarters in Antarctica. As a result, they aren't killed in the attack on New York City. This might be interpreted as a sign that Veidt is still fond of his former colleagues, and doesn't want them to die. When Daniel visits Veidt earlier in the story, Veidt does seem to be genuinely happy to see his old friend, which could lend some support to this idea; on the other hand, Veidt is nothing if not a duplicitous schemer, so he could have been putting on a show to allay suspicions.
However, the fact that Nite Owl and Rorschach survive the attack on NYC puts Veidt's plans in jeopardy, because they might tell the world what really happened, which would render Veidt's scheme useless and provoke the very war he was trying to prevent. In order for the plan to work, Veidt needs Dr. Manhattan alive and willing to go along with it, but the fates of the other Watchmen is largely irrelevant - in fact, it would be slightly better, from Veidt's perspective, if the other Watchmen were dead and unable to expose the plot.
So here's the question:
