The quote from Anthony Burgess's book "Earthly Powers" highlights the potential perils of religious motivations. While faith can inspire and uplift, it also has the capability to cause significant harm. The consequences of extreme religious beliefs can lead to actions that damage individuals and communities, sometimes resulting in irreparable harm to lives and relationships.

Burgess suggests that the intensity of religious fervor, when unchecked, can create conflicts and a divisive atmosphere, affecting mental and emotional well-being. This perspective encourages reflection on the balance between faith and its implications on human behavior, emphasizing the need for a nuanced understanding of religion's role in society.
