SpoilerHe protected the **** out of Brody at times. He wanted Carrie blown up because she is good at the job and he fears her. Thats why he either wanted her in that higher position(keep your enemies close) or completely gone. He gave the go ahead to shoot Nazir but, he knew damn well someone would warn him, likely Brody. Also, he wouldnt have been horribly upset if Nazir had been killed back then. Saul isnt just a mole, he is a head muslim ****ing terrorist. He ranks way higher than Abu ****ing Nazir.
