Franz Kafka’s quote highlights the dark side of human nature, suggesting that individuals often project their inner turmoil onto others. The idea conveys that when people are consumed by their personal struggles and demons, they may act out irrationally, causing harm to those around them. This reaction represents a misguided attempt at coping with their pain by inflicting it on others, showing a cycle of suffering and vengeance that exists among humanity.

In his work "Letters to Milena," Kafka explores the complexities of emotional anguish and interpersonal relationships. He illustrates how individuals can become trapped in their own psychological battles, leading to destructive behaviors. The quote emphasizes a universal truth about the human experience: when people do not confront their internal conflicts, the aftermath can result in pain and violence directed at others, underpinning the need for self-awareness and empathy in society.
