I can't understand why

People die, it's a fact of life there is nothing you can do about it. Cars get damaged and can be fixed, there is something you can do about that(hence the serious comments about cars). Not everyone on earth cares if someone they don't know, never met or didn't care about dies. Not everyone on earth is a nice person, not everyone believes in "god", not everyone has the same outlook as you.
My opinion and outlook on things...

Fara = There were and are better looking women out there, I never met her, who cares.

Billy = Loud, annoying, glad I won't have to hear his voice again, never met him, who cares.

M.J. = .... Glad he is dead, one less chillymo on the planet, F him! Never met him, who cares!

Me when I die = I will be dead, life will continue for someone else that never met me, didn't know about me, and could care less and those that did know me I'm sure will eventually get over it.

Agreed.
