The quote “When one has once accepted and absorbed Evil, it no longer demands to be believed” implies that when a person has accepted evil as a part of their identity or behavior, they no longer question its existence or reality. It becomes a part of their nature and they no longer need to convince themselves of its existence. They’ve internalized it to such an extent that it’s no longer a matter of belief, but a fact of their life.

This can be seen as a commentary on moral relativism, the idea that there is no absolute right or wrong, but that these concepts are defined by the individual or society. Once evil is accepted, it becomes normalized, and the person no longer sees it as ‘evil’, but just another aspect of life. This can be dangerous as it can lead to a lack of accountability and remorse, as well as a disregard for the impact of one’s actions on others.

In today’s world, this idea can be applied to numerous situations. For instance, in politics or business, some individuals may engage in unethical practices so often that they no longer see them as wrong. They’ve accepted these actions as a part of their job or role, and no longer question their morality.

In terms of personal development, this quote serves as a warning. It highlights the importance of constantly evaluating and questioning our actions and beliefs. It suggests that we should not allow negative behaviors or attitudes to become so ingrained that we no longer see them as negative. Instead, we should strive to maintain a clear moral compass and hold ourselves accountable for our actions.

Moreover, the quote also emphasizes the power of self-awareness and introspection. It pushes us to challenge our own beliefs and actions, to ensure that we are not blindly accepting something negative or harmful. It encourages us to always strive for growth and improvement, rather than settling into harmful patterns.
