question:
Ethical egoism is the normative ethical position that moral agents ought to do what is in their own self-interest. It differs from psychological egoism, which claims that people can only act in their self-interest.

Ethical egoism holds, therefore, that actions whose consequences will benefit the doer can be considered ethical in this sense.
