The Holy Father made some all too human mistakes. No mortal's completely free of sin, not even the Vicar Of Christ. But unless its of a mortal nature, even the Pope should receive God's mercy. And I would not want to speak ill of the dead.
(Denny Crane: "Sometimes you can only look for answers from God and failing that... and Fox News".) I totally agree. My personal opinion is that the Pope was quite ill for at least the last couple of years and that most of the decisions were probably being made behind the scenes by others in the Vatican and that he can't really be held personally responsible.
I do hope that whoever ends up becoming the new Pontiff will take a much different tack towards handling corruption within the Church hierarchy though. I think that covering up for guys like Bernard Law and his underlings seriously weakens the Church's moral authority.
