This quote by Aristotle suggests that a person who consistently engages in harmful or destructive behaviors is not only in conflict with society, but also with themselves. This internal conflict is due to the inherent human understanding of right and wrong, and the subsequent guilt, regret, or dissatisfaction that arises when one acts against this understanding. Essentially, a ‘bad’ person is at war with their own conscience, and this internal struggle is a constant source of unrest and unhappiness.

The ‘bad’ man here could refer to anyone who engages in actions that are considered morally or ethically wrong, or that harm themselves or others. These actions could range from lying and cheating to more serious offenses like violence or theft. When a person engages in these behaviors, they are often doing so in opposition to their own moral compass, which leads to an internal conflict or ‘war’.

This concept is highly relevant in today’s society, where we often see people engaging in harmful behaviors despite knowing the potential consequences. This could be seen in instances of substance abuse, where individuals continue to use harmful substances despite being aware of the damage they are doing to their bodies and lives.

In terms of personal development, this quote highlights the importance of living in alignment with one’s values and moral compass. When we act in ways that are congruent with our beliefs and values, we are more likely to experience peace and satisfaction. However, when we act in opposition to these values, we create internal conflict and unrest. This could be a powerful motivator for change, as recognizing this internal conflict could prompt individuals to alter their behaviors and strive to live in a way that is more in harmony with their values.
