The only evil elements that I'm fully aware of is killing and developing a nuke. It seems way underdeveloped and not much of the game. My first play through I played stealth and captured quite a few people for my base. If I didn't want the person then I just left them be, I only killed when I had to for survival or if required. For instance, I know of no way to capture a helicopter, so for those elimination missions you had no choice but to kill the pilots. My second play-through my style is to leave no one alive whenever I enter a mission, otherwise I avoid contact. I'm not even halfway through the story and the debris in my head signifying my demon level has lengthened quite a bit. Otherwise, I haven't noticed that much of a difference between the two sessions. Advanced equipment for the enemy has appeared sooner than before, but it's still way too easy. I wish there was a way to increase the difficulty from the beginning.
