Believed to be quite literally the most evil man in all of human history by Novus Ordoites and the Opus Dei 'crowd.'

Watching his sermon at the 1988 consecrations actually dispels most myths about his intentions, but most people don't bother to do that or for that matter any research and instead prefer to read rumors about him on r/Catholicism saying that he was demonically influenced and a 'rigid schismatic traditionalist.'
SSPX Attendee: Hey, have you heard anything about Archbishop Lefebvre? I just read a couple of his books and they're pretty interesting.

Opus Dei Attendee: Yeah I heard about him. He like, ate children alive and tried to elect himself Pope or something, right?
