In questions of praise, blame, reward, and punishment, the person's status as morally accountable and the act's voluntary attribution are central. Deliberately doing good is praiseworthy; knowingly committing a prohibition is blameworthy.
Assessing an action requires distinguishing intention, choice, the relevant command, and the circumstances of occurrence. Not every bodily result carries the same responsibility.
Intentionally injuring someone and causing injury through an involuntary accident, for example, are not automatically identical moral or legal cases. Such contrasts clarify why choice matters.
