I don't read Spider-Man all that much anymore. I read Superior, because I wanted to see Peter suffer, and I'll be reading Spiderverse but after that? Not touching Spider-Man comics ever again unless another Superior or Spiderverse happens.
The only way they can win me back is if they have Mephisto restore Peter's memory, reveals that Mary was forced to remember their past love together but had her "lips sealed" as per the deal(And Mary knowing that Peter pretty much killed their child and guilt tripped her into the deal), and Aunt May is made aware of Peter's horrible decision and really opens up on him about how he's shamed the family and have a period where she wont even look at Peter until she eventually forgives him. Than having Mary say that she still loves Peter, even after all the pain he put her through with his own selfishness and guilt, and forgives him even if she wont get back with him thus turning Mary into the Hero of the story who defeats Mephisto at his own game as he wouldn't be able to comprehend how Mary can still love and forgive Peter when she should hate Peter and want to see him suffer. Especially if Mephisto had Mary see the future where she had a child with Peter and than watching that future erased due to the deal.
This would all be because Mephisto wanted to truly destroy their pure love, so Mary forgiving and loving Peter even after OMD's truth is out in the open would be proof that Mephisto had failed.
