Who is Ali Bakir from Miramar and what is their importance?

Ali Bakir is an engineer, as well as a friend of bookkeeper Sarhan al-Bekheiry. He initiates a scheme to hijack truckloads of wool from the factory in which they both work, to sell on the black market. He convinces Sarhan by arguing that they are wasting their lives trying to live honestly. Ali is ignorant about politics, and when they are betrayed by the truck driver who is in on the deal, Ali tells Sarhan that he will do whatever the devil tells him to do. Sarhan interprets his words as suicide and quickly follows suit.
