Fault is, at its heart, wrongfulness. It is the idea that an action or a state of mind is wrong, blameworthy, culpable. If fault is required for a legal action to succeed, the argument would run something like “it is not just the act of causing harm which means you should pay compensation (in the civil law) or be punished (in the criminal law).
