" Before his uncle, Garrow, was slain by the Ra’zac months earlier, the brutality that Eragon had witnessed between the humans, dwarves, and Urgals would have destroyed him. Now it numbed him. He had realized, with Saphira’s help, that the only way to stay rational amid such pain was to do things. Beyond that, he no longer believed that life possessed inherent meaning—not after seeing men torn apart by the Kull, a race of giant Urgals, and the ground a bed of thrashing limbs and the dirt so wet with blood it soaked through the soles of his boots. If any honor existed in war, he concluded, it was in fighting to protect others from harm. "
