There was something that kind of disturbed me about his character.
Someone tries to assassinate him, then a cyborg killing machine comes to his house, and after a 10 minute discussion at the dinner table, the guy is willing to give up his career and life to fight for a cause he only recently heard about. Shouldn't he have been a little more skeptical?
I think Dyson was probably very open minded by nature and I wonder if he had already seriously considered the possibility that the microchip and arm had come from either an alien or future technology. Arnie telling him the story would merely have expanded on those considerations.
Hey! You're not old enough to drink! Now go and die for your country!!!
Yeah, now that I think about it, had everything gone according to plan, with them blowing up Cyberdyne, what would he have done with himself and his family afterwards? He'd have to go into hiding or allow himself to be arrested and just keep his mouth shut for the rest of his life while he rots in prison. Ballsy move.
Really what's funny is he was actually killed by stupid trigger happy cops. They shot him up when he was armed with nothing but the detonator to the bomb which wouldn't have gone off had it not been for them. In a way they caused a massive explosion to a building by doing that. I like this movie but those cops were villains.
