Final answer:
Good friends should not commit anything with betrayal, as it goes against the basis of trust and loyalty in a friendship, leading to negative outcomes and undermining the virtues of good character.
Step-by-step explanation:
Good friends should not commit anything with d) Betrayal, in which case they aren't good friends. The statement emphasizes the importance of loyalty and trust in friendships. Unlike betrayal, enmity, disloyalty, and animosity often lead to negative outcomes such as the result of wars between states, aggression between neighbors, and a lack of respect among family members. In the context of Aristotle's view on friendships, those that are based on the goodness of the characters involved and are supportive of virtuous development are considered perfect friendships. Betrayal would undermine the mutual goodwill that is essential for such a relationship to flourish.
