Would you like to discuss the Peasants Revolt in Germany in the 1520's that was begun by followers of Martin Luther and resulted in upwards of 300,000 deaths?
Or perhaps the Nazis who were also Lutherans who caused upwards of 20 million deaths? Of course it was Martin Luther himself who in 1545 first suggested burning all of the synagogues in "The Jews and Their Lies."
If you are referring to the Crusades, you might want to recall that all Christians in Europe were Catholic at that time.
I will be the first to acknowledge that BOTH Catholics and Protestants were responsible for bloodshed during the Reformation, but to attempt to assign any blame for this to Pope Benedict is insultingly ignorant.
Luther's evident hatred for the Jews in later years may have been his mind failing or just evil,I don't know.
The Crusades tended to be awfully messy and indisciminate in killing and pillaging,not too many actually made it to the Holy Land.
