Just an anecdote about Bakunin:
He was asked to translate Marx's Das Kapital to Russian language. Well, as he advocated this work of Marx, Bakunin promised to do it and received advanced payment. Eventually, Sergey Nechayev managed to induce Bakunin to "more urgent things" and Marx never saw the translation nor the money.
A nihilist in theory, a nihilist in practice.
