maybe i'm noticing this more as I just buried a friend today who was the exact opposite and am a little more receptive to it now.
why does it only have to matter if it affects you or your friends? tragedies are tragedies, regardless who is involved. people get shot every day, yes. people die every day. yes but does that mean we stop caring about others? that's one of the main things wrong with people these days, no human compassion and more apathy than anything.
and karma sucks yeah. but you can let it control you or not.
try being homeless, going through times where you don't have electricity, water or a cent to your name, burying 10+ friends, family etc from suicide, and a ton of other things i wont dare mention here.
you and i have also endured some of the same demons, internal/externally, physically, mentally etc. if i can still feel something, then there's hope for you.
