All three men looked at the world, saw what was wrong with the world, and developed thoughts on how to overcome such wrongs.
All three men were taken out or context and used by the state for the benefit of the state. Christ was used by the Pope turned politician, Marx was used by such wonderful figures as Stalin and Moa and Chavez, and Nietchze was used by Hitler.
I believe all 3 men would have been appalled by the misuse of their various philosophies.
At the end of the day though, most only identify with how the state presents each. They never really bother to dig down and see what they were all about.
Not at all alike, the three you've mentioned. I disagree, strongly. Christ did not intend to
change the carnal or corporeal world so much as his primary objective was arranging for some kind of immortality for mortals, and then only after their deaths . . . sort of undoing Eve's little boo-boo in the Garden. While his philosophies included a clear, easy to understand and follow code of moral behavior, said moral code was intended to qualify the souls of mortals for entering His Father's kingdom; making the world easier to live in was likely a side-effect. I do not believe Christ wanted to change the mortal world for the sake of making it a kinder, fairer place; rather, his teachings boil down to mortals living their lives in a specific manner which will award them eternal life
after death with an overarching theme of asking for and receiving forgiveness for sin.
Nietzsche was no messiah, no Christ-like figure, not really a prophet per se, either. He was a thinker, among the greatest to ever exist, and yet he was no man of action, as was Christ. Nietzsche made predictions about the mind and
souls of men. Predictions which turned out to be incredibly accurate if not possibly self-fulfilling to some degree considering the wide publication of his works. He was also a man of his historical era and all the associated baggage of that time period directly influenced his life and writings. Some believe Nietzsche was talking about himself when he wrote the character of
Zarathustra into being, but I don't think that's entirely accurate. One could also draw parallels between Nietzsche's Zarathustra and Christ, however, the differences are just to bitter and unmistakable. Where Christ intended to literally save every last man woman and child's eternal soul, Zarathustra as written by Nietzsche was content to prepare all men, women and children for the coming of a more perfect incarnation of human beings, and to convince all the people of the world to go quietly into extinction in preparation for their arrival. In this way, and the way in which Zarathustra cared for the lifeless tightrope walker, he cared only for the dead, while Christ cared for the living and what happened to their souls after death. I'd also get into Nihilism, but I'd be here typing out my post until dawn.
Marx, while a bit of a more cryptic "nut" to crack and understand than the others, was, if you bother to read
all of him, driven by hatred of specific races and classes and nationalities of people, pure and simple. There's no arguing he wanted to influence and change the world, it's just very obvious he wasn't out to change the world for the better, not by a very long shot. If Marx should be compared to any mythological or actual being, I'd suggest Satan or Lucifer or whatever they're calling old scratch these days would be a more apt huckleberry for that purpose. Marx is arguably directly responsible for the deaths of over a hundred million fellow human beings, possibly much more than that depending on how one fits abortion into one's analysis of Cultural Marxism and the shit China is pulling these days with organ harvesting.
In conclusion, I must agree with you that the words of both Christ and Nietzsche were both politicized and the men themselves underwent forms of apotheosis against their will after their deaths, but must disagree with you on Marx. Marx's grand meta-narrative ideology and panacea for healing the civilized world by revolutionary bloodshed was a thing politicized by his own hands within his lifetime.
To sum it all up:
Christ: gave hope to all who would listen.
Nietzsche: tried to convince all of mankind to give up hope; although not as malevolent as that sounds.
Marx: gave false hope to hundreds of millions; his were words of great deception.
