I have found claims about Vladimir Lenin saying near end of his life:
"I have been mistaken. It was necessary, I suppose, to liberate the multitude of oppressed people, but our method only provoked other oppressions . . . To save our Russia, what we needed--but it is too late now--was ten Francises of Assisi."
"I made a mistake. Without doubt, an oppressed multitude had to be liberated. But our method only provoked further oppression and atrocious massacres. My living nightmare is to find myself lost in an ocean of red with the blood of innumerable victims. It is too late now to alter the past, but what was needed to save Russia were ten Francis of Assisi’s" (Letters on Modern Atheism).
and also this variation:
I have deluded myself. Without doubt, it was necessary to free the oppressed masses. However, our methods resulted in other oppressions and gruesome massacres. You know I am deathly ill; I feel lost in an ocean of blood formed by countless victims. This was necessary to save our Russia, but it is too late to turn back. We would need ten Francis of Assisi.
But I did not find any source of this quote. Washington Post article says it was said "in a conversation with a Hungarian priest whom Lenin knew from his boyhood." I also searched for "Letters on Modern Atheism" from DesiringGod.org quote but found nothing. I did not find this quote on Wikiqote. I also searched They Never Said It: A Book of Fake Quotes, Misquotes, and Misleading Attributions and found nothing, but I do not own the book so I do not see all quotes.
Did Lenin say this?
