> In no future is it better for other people to be unhappy. Then explain why some people are criminals or parasites on the system it it's better for everyone to be happy? Why take advantage of others if it's better overall not to do so? My guess is because some people don't care about others. Psychopaths generally fall into that category. Question is what they would do if they made up all of society, which means everyone is understood to be looking to take advantage.
