Power is thier highest value. It is the center of their Utopia.

A Christian recites "Rest in peace" because he dreams of a utopia where all is right with the world, where he can see is family and friends, and he can be at peace, and live contented.

Communists don't want peace.

They want power.

The "heaven" of a Communist is just Mao: wild, murderous, unaccountable power, with the ability to cause unlimited human misery, while sitting on your ass and being fat.
