At the heart of agent-centered theories (with their agent-relative reasons) is the idea of agency. The moral plausibility of agent-centered theories is rooted here. The idea is that morality is intensely personal, in the sense that we are each enjoined to keep our own moral house in order. Our categorical obligations are not to focus on how our actions cause or enable other agents to do evil; the focus of our categorical obligations is to keep our own agency free of moral taint.
