It makes the difference in how things play out in the aftermath. The injury may not change, but if the harm wasn't intentional, the wounds it creates aren't impossible to heal. No matter what they may feel like... or what you may feel like. I've tried to make people hate me before, when I thought they should. The good ones rarely accept your own self-loathing as enough of a reason to condemn you.
Morality doesn't benefit a dead man.
It's not especially different from where we are. Just more heavily populated... and with less large threatening creatures.
