Garnier de Naplouse
From Assassin's Creed Wiki
Garnier de Naplouse is the second templar assigned by Al Mualim for Altair to assassinate. He is a doctor and Grand Master of the Knights Hospitalier in the city of Acre.
During your pre-assassination investigations, you learn that he is a false doctor. He treats his patients cruelly by conducting experiments on them, torturing them, and not allowing them leave (even going so far as having his men break their legs). In order to not draw attention to his acts he forcefully takes his patients from the surrounding cities of Jerusalem and Damascus.
During his monologue after you assassinate him, he speaks of how he was actually helping people. He claims that the people he took were among the poorest and most ill of the other cities, and that many have recovered and thanked him for his help. He says his methods were necessary to free people from the shackles of their old lives.
