I think for them... they have few mentalities of a normal being, or mentalities succumbed to their growing up in their society.
1. Die young and stay memorable (like some of the earlier peers)
2. The depression of fame
3. Some kinda pain, like drugging, etc that have caused them to juz get wasted completely...
I sorta believe they were thinking of point #1 complemented by the other points... People remember them more clearly cos they die while they were so young and at their highest point in career.
My 2 cents... 8)
