Neither and both. Morality means the individual’s leap to meaning in life, it is an ideology that in theory can be non-violent if the individual decides martyrdom for that meaning is part of the meaning of their life. However, by this meaning of martyrdom, they are being violent to themselves, so morality often cannot eliminate violence as one of its attributes but at least violence is not a necessary attribute of morality. Ethics is essentially a group’s morality, it is the social construct by which a social group arbitrates morality conflicts among members of its group so that the conflicts do not disrupt and destroy the group’s ability to exist and maintain its social construct meaning and power. By necessity, ethics must involve an attribute of violence: violence against those social groups with a different ethics or against individuals with an inconsistent morality. This final attribute is not obvious since usually most members are not involved in the enforcement attribute of ethics. Even an ethics of non-violence will be enforced by violence against those who oppose it. If an ethics has no violence element, it is simply a social construct ideology that makes nice parlor conversation but is meaningless in the struggles of life and eventually will achieve social suicide by disappearing from history.
All social groups have a code of ethics including such as the mafia, the Russian mob, the lowest street gang on the West Side of Chicago, and et al. In my experience, illegal ethics are more honest, consistent, and loyal to their ethics than the vast majority of moral busy-bodies that enforce “legal” codes of ethics that are in denial of their violence. However, complying with the code of ethics of the mafia for example does not make you a moral person. Morality and ethics are not the same. One can be moral yet unethical and the reverse. Law is an ethics with a monopoly on violence.
Language is “objective” when it describes by means of hypotheses subject to Ockham’s Razor and makes quantifiable predictions or at least correlations that can be tested and falsified in repeatable parameter controlled experiments. Objective truth is pragmatic: its truth is ontologically real as long as the words of its truth work to solve the described problem. “To be is to be the value of a bound variable” — Willard Van Orman Quine. For example, “[o]n pragmatic principles, if the hypothesis of God works satisfactorily in the widest sense of the word, it is true.… The problem is to build it out and determine it so that it will combine satisfactorily with all the other working truths” — William James. “Subjective” misses one or all of these attributes.
