what's missing in this discussion is a mention that humans are well capable of wiping out other species and have done so fully aware. we're also perfectly capable of wiping each other out for no reason other than status.
I keep engaging in morbid thought experiments to figure out how certain people feel when they commit certain acts and whether I would be able to do the same provided the circumstances are hard enough. A few examples:
if I could blink my eye and all the valuables and money of everyone in this room/house etc would suddenly be mine, how much would that be, and would I do it?
if I could blink my eye and everyone in that room/building would vanish from the earth would I do it?
if I could blink my eye and 2/3 of the earths human population would be wiped out by x/y/z would I do it?
if I would be forced to work in a concentration camp being tasked with horrid acts against humans ... maybe with the alternative of being killed myself or having my family etc (spin that further what if I didn't have a family and just my dog that would be sacrificed if I were to refuse) ...
...
the answers always terrify me.
