"I'm not an assassin, atleast not anymore" is a phase I heard Desmond say in the first game, the Templar guy says "you are an a assassin" but how can Desmond be an assaSsin if he haven't even gotten training yet? Is this wrong?
He at least got some training as a child, but ran away at 16 like al-Assas said. He thought it was too crazy of a group and didn't know the reasons of why it was so important.
