IDEA
Ask whether moral blame should track what a person could control, rather than everything that happened.

A control principle connects blame with what someone could understand, choose, or influence. It asks whether holding an agent responsible is fair when a relevant feature lies beyond their power. Control comes in degrees and can concern an action, a foreseeable risk, or later opportunities to respond.
Control has an informational side and a practical side. Someone may have authority to stop a process but lack the knowledge needed to recognize its danger; another may understand the danger while lacking authority to intervene. Responsibility can also concern failing to acquire information when a role required it. This makes assessment sensitive to reasonable expectations and available options. Asking what the person could actually know and do is more useful than assuming unlimited foresight or power.
Imagine a technician reporting a fault promptly but lacking authority to stop the system. Compare a manager who receives the same warning and can act. Both know the problem, yet their practical control and role responsibilities differ.
Control is not the only possible basis for assigning duties after harm. Someone may owe assistance because of a relationship, benefit, or role without being culpable for the original event. Distinguishing blame, causal contribution, and remedial responsibility prevents the question “Who is responsible?” from hiding several different questions.
In an imagined organization, a junior worker reports a defect to the person empowered to fix it. Compare their obligations before and after the warning. The manager now has relevant information and control, while the worker may still have a responsibility to follow up if the danger persists. These reasons arise at different times. Mapping the sequence helps distinguish culpable neglect from limited capacity and identifies where the institution should improve authority, communication, or review.
Can equal fault create unequal duties of repair?

Moral luck creates tension with the principle that blame should depend on control.
These explanations synthesize philosophical discussions. Examples illustrate the ideas; connections to practical situations are editorial interpretations.
