Catechism number 1736

Every act directly willed is imputable to its author:

Thus the Lord asked Eve after the sin in the garden: "What is this that you have done?"²⁹ He asked Cain the same question.³⁰ The prophet Nathan questioned David in the same way after he committed adultery with the wife of Uriah and had him murdered.³¹
An action can be indirectly voluntary when it results from negligence regarding something one should have known or done: for example, an accident arising from ignorance of traffic laws.
