A.S. Byatt's quote, "There will always be people who will slash open the other cheek when it is turned to them," suggests a perspective on human behavior that recognizes the darker tendencies in people. It reflects an understanding that, rather than responding to kindness or forgiveness with generosity, some individuals may choose to retaliate with violence or betrayal. This highlights a fundamental aspect of human nature, where one can find cruelty even in situations that call for compassion.

This insight points to the complexities of human relationships and the unpredictable nature of interactions. Byatt's observation serves as a reminder that, despite the noble ideals of forgiveness and peace, there are always those who may exploit vulnerability for their own gain. The acknowledgment of this reality adds depth to the exploration of themes such as trust, power, and moral choices in her narrative, prompting readers to reflect on their own experiences and societal dynamics.
