They don't know what is happening here? How is that the case with the blessed in Heaven? What are you basing this on?
By Catholic standards, Lenin should be a saint then too.
That's not how it works. The recognized (canonized) saints of the Church's lives of sanctity are well documented. Lenin's wicked life is as well, so unless he repented, and we don't know it, there's a good chance he's in hell.
Need to reformat and repost my reply. Waiting on mod to delete.
