I'm confused here and have a good question because of this...

Why is it that everyone cares? Like I'd understand if it affects them directly or someone that they know and talk to... but when it isn't why do people care when other people that they don't know die from a murder and when a criminal gets caught? Even find myself caring and feeling bad but when someone random comes and says that they know of someone who died or I hear about someone I never knew or would've ever knew died in a completely other state, why? O_o

It's just confusing cause while I do feel sorry, I'm going to forget about it a week or so later and go about my day as usual and people die everyday and crimes happen all the time yet Idon't care untill it becoems a big deal for a short bit or untill it affects me or the people I know (and even those I don't really know but still talk too, like you guys) directly...

This has been bugging me for a very long time so I hope to be enlightened on why we all care and discuss it so much instead of just all saying that it's quite sad and that they feel sorry for the family and move about their day as usual... Cause even I tend to find myself caring so much about these things yet I can't explain the reasoning behind it. :/

I can't really explain this question without looking like a complete duchebag about this so I'll leave it at this and hope you all get the general idea of what my question is...

EDIT: I do understand sentimence and shit, but excluding all emotional thinking... Why?
