Robert Paul Wolff said this quote

“ Both Marx and Nietzsche understood that moral outrage is the last resort of the powerless. That is why Marx refused to issue moral condemnations of capitalism, preferring instead to lay out, calmly and ruthlessly, his reasons for believing that it is destined to be replaced by socialism. And that is why Nietzsche mocks Christianity for portraying its crucified Saviour as bait wriggling on a hook to catch unsuspecting souls. ”
