yo you might like Kohlbergian stuff, basically seeks to explain moral development in psychological terms at a more human level, it may help in dragging ethical considerations back into the realm of what applies to real humans

Beyond that, I have a relative who is more than interested in ethics and morality, and they generally do not like utilitarianism because 1) pleasure isn't universally good, it requires specific contexts in order to be valuable, there's no reason to value it universally and 2) making an immortal sentient computer box that can masturbate itself indefinitely does not add infinite meaning and good to the universe
