When the death of a disabled infant will lead to the birth of another infant with better prospects of a happy life, the total amount of happiness will be greater if the disabled infant is killed.

Therefore, if killing the hemophiliac infant has no adverse effect on others, it would, according to the total view, be right to kill him.
