Final answer:
The important difference between instrumental causality and moral causality is the intention behind causation.
Step-by-step explanation:
Instrumental causality refers to the causation of an action based on the means to achieve a desired outcome, while moral causality refers to the causation of an action based on the moral intention behind it. The important difference between them lies in the intention behind the causation. In instrumental causality, the focus is on achieving a specific outcome, regardless of the morality of the action. In moral causality, the focus is on the moral intention and the impact that the action has on others.
