Uniforms such as collars, trench coats, or jackboots serve as symbols of authority that can make individuals feel empowered to act cruelly without experiencing personal guilt. They act as a psychological shield, allowing wearers to distance themselves from the moral implications of their actions.

According to John Boyne in his book The Boy at the Top of the Mountain, "Collars, trench coats or jackboots – uniforms allow us to exercise our cruelty without ever feeling guilt." This highlights how uniforms can dehumanize individuals and facilitate oppressive behavior, emphasizing the dangerous influence of symbolism in fostering cruelty.
