I agree, it was a brave decision to take, and he has undoubtedly done it with the overall good of the church in mind. I recall news footage of John Paul II, and thinking it was actually cruel to wheel him out in public and expect him to speak, hold a Papal Mass, that sort of thing, when he was so very ill and frail he could hardly speak.
I have noticed though that in various places the end of the world people are trotting out the Petrus Romanus prophecy. Didn't take them long.
