Jesus does not divide the world into the moral "good guys" and the immoral "bad guys". He shows us that everyone is dedicated to a project of self-salvation, to using God and others in order to get power and control for themselves. We are just going about it in different ways. Even though both sons are wrong, however, the father cares for them and invites them both back into his love and feast.
