JPII asked St. John to bless and protect Islam. He kissed the Koran. He prayed to non-Catholic gods publicly. Speaking of the rosary, he tampered with it. He appointed and protected pedophiles.
I am certainly a sededoubtist, at least a material sededoubtist, but if Pope Francis I is, indeed, a true Pope, then I think that it is a strange use of the Keys of the Kingdom of Heaven for him to declare someone to be in Paradise who is, in fact, not there. So, if Pope John Paul II is really in Heaven, which is life eternal and he, at this very instant, is beholding the Beatific Vision and is in the presence of the One and Triune God seeing and experiencing His very essence and being, then such demands an explanation. Now, some atheist authors, a long time ago (late 1980s), accused Pope John Paul II of being a "closet traditional Catholic" and tried, in a book, to present evidence of such. Perhaps JP II was, in fact, a traditional Catholic, at least in his heart. As for all of his apparent apostasies and/or heresies, then neo-cons can explain all of those, and you haven't far to look for that.
