From
this post, some thoughtful insight by
guarded_logic:
Darim is introduced as an accomplished marksman that kills Genghis, but then he starts acting like kind of a douchebag.
He travels to Alamut to get his brother and finds out he was murdered in Masyaf, which means they were previously lied to and his parents are almost certainly walking into a trap. What does he do? Stay in Alamut. Then his father comes and tells him that his brother, mother and "practically uncle" Malik were killed by order of the current leader of Masyaf. Which puts Darim in almost the same position as Ezio - with one parent dead and the other in shock, but what does he do? Nothing. He's the son a Grandmaster and the best arbalist they have and he doesn't try to avenge his family? Start a revolt? He could've at least collected a hundred feathers for Altair or something. But instead he's all "Daddy, why you no love me anymore?" and goes on a Eurotrip until his father gets his power back.
He seems all the more indifferent to both his family's and the Brotherhood's cause when compared to Tazim.
OH, MY BEATING HEART ♥
Also, some developer is all liek,
"Yea bro, books are canon." To which I reject your reality and substitute it with my own where Malik lives peacefully forever, pushing novices off of tall towers of which they sometimes fall into haystacks.
