Lets now look at why El Hajj Malik El Shabazz (Malcolm X) was assassinated.
Straight to the point...because the FBI and the US govt. viewed him as a threat to national security. Why?
Because he was no threat when he identified himself as a Black nationalist. No one takes Black nationalists seriously. Black nationalists do not even take Black nationalism seriously.
Once he renounced Black nationalism, he embraced Pan Africanism. This is evident in his autobiography. Just witness the numerous heads of state that he visited. Virtually all were noted Pan Africanists who also were either assassinated or deposed in western orchestrated coups.
Another reason is because he moved beyond the civil rights movement to initiating a Human Rights campaign. He stopped speaking in terms of race, and into expressions concerning our Humanity.
His conversion to "orthodox" (whatever that is) also was part of the equation, on a personal level, but it was his move toward Pan Africanism and Human Rights that posed a threat to Ameriklan interests.
Think about it. How many Pan Africanist or Human Rights activists from the 60s or 70s are still alive?
Then ask yourself. How many Black nationalists from the 60s or 70s are still alive?
What do those who are still alive and what do those who are deceased have in common?
