You sure? Seems everyone is being manipulated by everyone in Deus Ex. As for "their orders are to kill you", so? If you play the game properly, you can talk down the Leader of the Humanity First movement. Seems Jensen is quite the talker, y'know? Everyone is open to some sort of reason. They're not zombies. Also, you can get by on no-kills with just a pistol. Fully upgraded (and even partly upgraded) it's a great weapon.
