What concept focuses on making decisions for the greatest benefit to oneself?

The concept that focuses on making decisions for the greatest benefit to oneself is ethical egoism. This ethical theory posits that actions are morally right if they promote an individual's own interests. Ethical egoism encourages individuals to consider their own welfare and to act in ways that will yield the best outcomes for themselves. This can include prioritizing personal goals, desires, or well-being in decision-making processes.

In contrast, utilitarianism is centered around the idea of maximizing overall happiness or benefit for the greatest number of people, rather than focusing solely on the individual's interests. Deontology emphasizes adherence to moral rules or duties without regard for the outcomes, and altruism is characterized by selfless concern for the well-being of others, opposing the idea of prioritizing one's own benefit.
