"... Do you believe people should die for their mistakes ..." People do all the time. 
That is simple nihilism and giving up. Bombs go off all over the place, so who cares? Planes crash. So what? Happens all the time.
What are we, animals on the savanna? 
It's a response and a belief but not an answer. People "all the time" do great things. 
It's just a simple and frankly dumb response but one that people utter "all the time."
