In this paper, I highlight three objections to vice-based accounts of moral evil: (1) the worry that vice-based accounts of evil are explanatorily inadequate; (2) the worry that even extreme vice is not sufficient for evil; and (3) the worry that not all vices are inversions of virtue (and so vice-based accounts will struggle to explain the “mirror thesis”). I argue that it is possible to respond to these objections by developing a vice-based account of evil that draws on insights (...) from virtue (and vice) epistemology. In this way, I seek to defend the strategy of understanding evil in terms of vice, and to provide guidance on how best to develop such an account. I also briefly consider what vice-based accounts of moral evil might imply about evil in other normative domains where it is common to talk of virtue and vice, including the possibilities of epistemic evil and aesthetic evil.
