But what I said was correct. We don't know that Jackal is the villain. From what we know, it would make some sense, but at the moment it's just speculation. Suspecting something to be true isn't knowing something to be true.
People have been saying for a while the man in red could be Mephisto.
However, in today's issue of Spider-Man/Deadpool, Mephisto turns up and it's revealed he remembers the deal (essentially retconning One Moment In Time's assertion that Mephisto deleted himself from the deal), he visits Peter in a dream and reminds him that he lost the battle for his soul.
