It's true. this is just humanity tho.
Most every american would happily kill you if there was some nebulous chance that it might marginally improve their lot in live, marginally avoid some loss, or marginally increase their safety. Most people in other countries would do no better, and maybe worse, if they wielded the power and influence we were born into.
This isn't theoretical, we see it every damn day. Humans are fuckin scary man.
