"Aristotle on the Friendships of the Bad"

Aristotle considers a puzzle from Plato’s Lysis: can bad people be friends? Aristotle offers an affirmative response. Bad people can be friends on account of pleasure but, they cannot participate in complete friendship. Aristotle seems to suggest bad people cannot be friends at all, for they do not even love themselves. Aristotle distinguishes between becoming friends and being friends. Bad people can very well become friends, but their friendships lack stability; they cannot be friends.
