"If a hiker gets lost in the mountains, people will coordinate a search. If a train crashes, people will line up to give blood. If an earthquake levels a city, people all over the world will send emergency supplies. This is so fundamentally human that it's found in every culture without exception. Yes, there are assholes who just don't care, but they're massively outnumbered by the people who do."

(The Martian by Andy Weir)

"The Buggers have finally, finally learned that we humans value each and every individual human life... But they've learned this lesson just in time for it to be hopelessly wrong—for we humans do, when the cause is sufficient, spend our own lives. We throw ourselves onto the grenade to save our buddies in the foxhole. We rise out of the trenches and charge the entrenched enemy and die like maggots under a blowtorch. We strap bombs on our bodies and blow ourselves up in the midst of our enemies. We are, when the cause is sufficient, insane."

(Ender's Shadow by Orson Scott Card)
