The ideal ethical decision is the one that creates the most happiness and the least amount of sadness. In the decisions we make, Mill would say that we need to weigh the outcomes and make our decision based on that outcome that benefits the majority. .
Second, Mill says that all ethical decisions should be based on pleasure. This statement becomes questionable when Mill states that pleasure is the sole requirement for happiness. Pain indirectly effects happiness. Pain is an indirect factor because is not the object of one's happiness, but is an obstacle which one must overcome to gain it. If one is to avoid all pain in his or her life, then how will that person truly know what true pleasure feels like? True pleasure comes only after experiencing pain. If a person always wins a race, does he or she feel true pleasure each time they win or does it turn into a feeling that they come to expect? If there is a student who loses races constantly, will his happiness be greater when he finally wins? The rewards and pleasures of the second person would greatly outweigh the feelings of happiness the first had because he or she knows how it feels to be defeated. The second person knows the pain that is received because he or she already experienced failure, therefore he will recognize the pleasure that comes with winning. Using this same setting, would it be better for the second person to run in races filled with people who are not matched in skill just so he may always win or should he or she race individuals who are equally matched? Although the first would produce pleasure, the second example would yield the greater amount of pleasure due to the understanding that the competition was evenly matched. Both of these examples show that pain can ultimately cause pleasure, and in some cases the presence of pain will increase the feeling of happiness. .
Another point were there is disagreement is when Mill justifies the pursuit of pleasure by saying "actions are right in proportion as they tend to promote happiness; wrong as they tend to produce the reverse of happiness.
