We've been told that not all the aliens in a species that want to kill us are bad. Some are supposedly against their own race on various matters. While these guys wont shoot at us at first what happens if we go trigger happy on them? Will the rest of their supposedly pro-human faction chase us for a little? Ex: I'm fighting the Fallen's House of Devils faction(or whatever their called) and I accidentally shoot a white coat. Now because I've done that their whole faction will take aim at me for a few days. They'll eventually forget it but for those few days they'll divert their attention to chasing me down. Would be kinda cool...in my personal opinion.
