Are the Assassins doing the right thing? Are the Templars doing the right thing? Are both of them right or wrong?
The Assassins fight for freedom and eventual peace, while the Templars fight for order and eventual peace. Both operate in the shadows, and both want the same thing. They both want peace. They have different ways of getting to it, however. The Templars want world peace, but they believe that the only way to achieve that is to brainwash everyone. The Assassins also want world peace, but they believe it can only be achieved through pure freedom.
Who is right or wrong? Are both right? Are both wrong?
