Faisal is here to get his jihad on.

Faisal is perfectly open about how cool and fun
he thinks it is to be able to throw his weight around
as a member of Al-Hisbah. He brags about everything
from his Porsche back in Jedda to the number
of Shiites he’s bagged. Once he’s back home in Saudi
Arabia, he’s going to brag about this war like it was
spring break.

He happily tells anyone who listens about his
“slutty” Yazidi concubine, a kidnap victim who ran
away at the first opportunity after he raped her. It is
intolerable to him that ISIL officials are dragging their
feet getting him a new concubine.

Besides these fine qualities, Faisal is greedy. When
he hears about Rassam paying in gold, he wants to
discover its source

He is a handsome man with a cheerful disposition that comes from having better equipment and cleaner clothes than others.
He receives care packages from home since there is almost nothing for his money to buy in the Caliphate.
