Why do the Awesome Die Young?

Why does everybody who is freaken way ahead of their time, prophetic, and really out to change the world get killed (always mysteriously and never without conspiracy)?

MKL, Tupac, JFK, Malcolm X, Bobby Kennedy, etc. I am sure there are hundreds of others I am forgetting.

Anyways have some words of wisdom from one of these folks.

"Peace is a daily, a weekly, a monthly, process, gradually changing opinions, slowly eroding old barriers, and quietly building new structures."

-John F. Kennedy Jr.
