Imagine you are in a public park and you see an obese rich kid eating a triple-decker ice cream cone. Nearby you see three starveling waifs from the local orphanage looking enviously at the rich kid with his ice cream cone. As a utilitarian this is a situation where happiness/unhappiness is front and center.
What should you do in this situation to make the world a happier place, and does that turn out to be the right thing to do?
You need to consider what options are reasonably available given the circumstances, and those circumstances include the facts about you also. Then calculate, roughly, which option would produce the most overall happiness by spelling out the likely consequences of the available options. Finally say whether that answer is the morally correct one, and why/why not
