Just remember, there are some people who literally cannot see the emotional difference that's obvious to most. Call it sociopathy or being "on the spectrum" or what have you, for them its like watching a black and white TV picture of a world in color.

They may care very much about life, see two events one with many deaths, one with few, and a everyone inexplicably spending all of their money fixing the few and seemingly ignoring the obvious cheap fixes for the many.

So because they care (and not because they don't) they reach for their superhero capes and go try to help.
