Vonnegut also shows a change in the painter's perspective on death which evokes his altruistic mindset to consciously volunteer his own life for the upcoming generation.
From the beginning, the painter has had a very distinct point of view on the society that he lives in and illustrates it in his mural "The Happy Garden of Life".
But, most of all, happiness comes from knowing the certainty of waking up the next day, safe and sound.
Everyone wants it, but no one ever is willing sacrifice their life, especially for the contentment of others.
Given these points, it can be said that the author wants the reader to realize that an individual's compromise of happiness generates the development of a very altruistic mindset, as the actions are originated from a conscious state of mind, which results in rational decision making and positive outcomes.
Vonnegut uses the character of Wehling to represent the sacrifice of one's life to save the life of others.
He is also very shaken by the fact that someone also will have to die for the survival of at least two of his new borns.
He has not been prepared for that and expresses it to the doctor by saying "I don't want my grandfather to die, either".
Even though, he is sarcastically expressing joy upon hearing the news of his triplets being born by saying to the doctor, "What man in my shoes wouldn't be happy?
", he is extremely depressed by the fact that he will not be able to see the faces of his new born, as he will be ending his own life for there survival.
