Pol Pot was a visionary who wanted to create an agrarian utopia. He personally oversaw the killing of more than a million people.
Thomas Jefferson was also a visionary who wanted to create an agrarian utopia. He was just a slave-owner and an adulterer.
Zeno, the founder of the stoic philosophy, wasn't really a visionary but he believed in an agrarian utopia. He thought it was more creditable to operate from within society and to follow a fairly reasonable code of personal ethics that made him stand out, but didn't get him in trouble. He never killed anyone. He never owned a slave. And, he never broke a vow. (So far as we know)

See you at the stoa.
