Answer:Integrity versus despair
Explanation:This is the last stage or final stage in Erik Erikson's stage theory of psychosocial development.
Ego integrity versus despair begins at the age of 65 and ends at death. It is a time in which a person reflect on their lives and think about what they have accomplished , if a person feels like they have accomplished enough in life and have led a successful life , they will develop integrity.
However, if a person feels like they failed and there are things that they feel they should have accomplished but did not accomplish , they will experience despair.
*reflecting on the mistakes he made in his life as well as the dreams that went unfulfilled.* Wilbur is experiencing despair.
