Answer:
Leo
Explanation:
According to Erikson's theory, there is a stage of human development called "Integrity versus Despair." This stage happens to the elderly and is described as the conflict between the integrity and the despair of the ego, the former being a sense of satisfaction when reflecting on a productively lived life, and enabling the elderly to accept their own life, allowing acceptance of death and thus developing the virtue of wisdom. The following refers to the sense that life was of little value, with despair and disgust at the inability to revive it.
Accordingly we can say that Leo is in the ego's despairing stage, because he is very embittered and angry at his past choices and even at what he lives in the present.
