Therein lies the contradiction of his beatification.   One cannot perform miracles unless they are touched by "God". The power to heal is the "power of the Almighty" flowing through the hands of a simple man. Yet, "God" didn't give him the wisdom to see how wrong it was to allow all those victims to go unnoticed, unbelieved, unprotected, uncompensated all for the sake of preventing scandal? 
I personally do not believe any god would have cared one bit about a scandal, if it meant protecting those who cannot protect themselves. By ignoring the wrongs to children, JP2 was protecting himself and the church which allowed him to live in such opulence. Ignoring the crimes was just as criminal. 
I think JP2's failure to speak out/act accordingly against the crimes committed far outweighs any "miracle". His "halo" should be removed.
