How to be a Universal Pastor

The Holy Father strikes just the right note here, I think. Some will object that in addition to praying for the victims he also prayed for mercy for the authors of 9/11, but surely this is in keeping with the example of Christ and St. Stephen. They obviously did not approve of or make excuses for the evil done. Neither does JPII. Whereto serves mercy but to confront the visage of offense?
