Throughout the series we have been told that the assassins are the good guys and the templars are the bad guys. That the assassins fight for freedom and the templars want to rule the world. But what if the templars really are the good guys? Sure, Desmond saved the world and everything, but now he is dead and some evil b*tch has got the power to rule the world. Maybe the templars knew about Juno and her motives and they were trying to stop her? Maybe that is why they wanted to find all the pieces of eden, but instead the retarded assassins who had no clue stopped them from doing what was right.
I mean everytime you assassinate a main templar target and they give you their final speech, they are always like "You don't understand what you have done.. /facepalm", and then you kill them. Its like they are trying to muthaf*cking explain to the retarded assassins that if they keep killing the templars something bad will happen to the world, but the stupid assassins just keep on killing them.
What did the assassins accomplish in the end? Now the world is ruled by some crazy alien.
