Axiological ethics?
The branch of ethics dealing primarily with the relative goodness or value of the motives and end of any action.
"In philosophy, axiological ethics is concerned with the values by which people uphold ethical standards, and the investigation and development of theories of ethical behaviour. Axiological ethics investigates and questions what the intellectual bases for a system of values. Axiologic ethics explore the justifications for value systems, and examine if there exists an objective justification, beyond arbitrary personal preference, for the existence and practise of a given value system. Moreover, although axiological ethics are a subfield of Ethical philosophy, axiological investigation usually includes epistemology and the value theory."
