i've learned that people are in it for themselves and money > all
lets put it this way, if you had the choice of pushing a button, and upon pushing it you would end some randomly selected person's life halfway across the world and receive a million dollars for doing so, you'd push it. don't even act like you wouldn't. there's no accountability, no skin off your back. you're just looking out for #1. you'd be happy with your 1mil even though you know you killed someone to get it. you just don't know who. sure, you didn't exactly murder them face to face in exchange for currency. but what's the difference?
human nature is a funny, and disgraceful thing.
