"While in service to the First Order, Finn was seen by his training cadre and his fellow soldiers as one of the best stormtroopers that the First Order had to offer. His instructors saw him as loyal to the First Order, as well as dutiful, brave, intelligent, and possessing the strength necessary to be a great stormtrooper. Finn was trained to believe that the New Republic was depraved and that the First Order was necessary to bring law to a lawless galaxy, and everything he had seen of the galaxy was filtered through his training; the First Order showed him only what they wanted him to see, but he did not doubt its truth. Nonetheless, though as a cadet he was eager to be deployed and see the galaxy so he could serve the First Order and Supreme Leader Snoke, he was plagued by doubt. That doubt came to a head on Jakku, when he refused to fire on the villagers and deserted from the First Order.[4]"
