He's the biological child of a Syrian muslim immigrant and an American of Armenian descent.

And then he's adopted into a sort of purely American life.

There's a whole lot of outsiderism to unpack there, and while he adored his adopted parents he seems to have struggled with his own fatherhood roles etc.

He was aloof and had a sort of paradoxical relationship with conformism -- he was consistent to his own personal design (the wardrobe full of identical outfits, the repeated leasing of the same kind of car) -- but rejected the conformism of others.

Really a lot of his manner -- including some of his more sociopathic traits -- could be explained by early disruption in life. He had quite a tough start.
