Yup, I've tried it. Strange so many people went with killing Reynolds, there was no doubt in my mind that what he was telling me in the cutscene was what we wanted to avoid.
BIS went out of their way to make Reynolds look like a bad guy. He is dressed entirely in black. He has black eyes. He has a scar down his face. The trailer was pretty focused on making him seem malevolent.
Call me crazy, but when he started ranting about how knowledge of Takistan's nuclear program would end the world, I was a little reluctant to just take his word for it.
EDIT: just realised this thread was dug up. Oh well.
