That’s a question that philosophers have been writing about for centuries! There is no simple answer. I suppose the best answer I could give is: try to think about the downstream effects of the choice you face, and think about what the world would be like if everyone made a particular decision. Politically speaking, I think the best answer is: decisions should be made by the people affected by those decisions. People more affected should have greater say.
