When i approach decisions and take action based on what is in the best interest of others, i am applying which ethical theory?

When I approach choices and make a move in light of what is to the greatest advantage of others, I am applying Altruism moral hypothesis. It is a moral convention that holds the ethical estimation of a person's activities depend entirely on the effect on different people, paying little respect to the outcomes one's own particular self. Auguste Comte, the french author of positivism trusts that people had an ethical commitment to repudiate self intrigue and live for others.
