In the book "The Royal Family" by William T. Vollmann, the author explores the complex nature of evil and its subjective interpretation. He suggests that what one person perceives as evil may vary significantly from another’s viewpoint, highlighting the complexities of moral judgment and personal beliefs. This subjectivity raises questions about the foundations of morality and ethics in society.

Vollmann contrasts the concept of evil with the notion of legality, suggesting that while evil may be seen through a personal lens, legality is defined by societal rules and norms. This distinction emphasizes that actions deemed illegal do not always correspond to moral failings, as laws can sometimes support unethical behavior. Through this examination, the author invites readers to reflect on their own moral perspectives and the implications of societal laws.
