Assassins, they kill for a cause not for money, plus the word comes from the arabic Hashshashin a group a militant muslims who murderd crusaders and muslim rulers they dissaged with between 1090-1270. The word Hashshashin meant, eaters of hashish and in the middle ages it was a synonym for outlaws, later french crusaders took the word home and transformed it into assassins. So when you all are playing assassins creed later this year don´t forget that all those killers are high on hash
