The problem with this is that not everyone finds the same actions or in-actions to be moral or immoral. Some cultures still find it morally just to chop the hands off a thief while others find this to be immoral. Some find homosexuality to be immoral based on their religious beliefs while others with similar or completely different beliefs find nothing wrong with it. One scenario I find fascinating is The Trolley Problem. This states: You see a trolley flying down the track and is about to run over five people. There's a switch that can be thrown to divert the trolley, but instead of killing the five people, it'll kill one person. Would you throw the switch to kill the one person and save the five? An overwhelming majority of people say that yes they would. A variation of this is The Fat Man: You're standing on a bridge and see a trolley flying down the track and is about to run over five people. A large enough mass would stop the train and save the five people. A very fat person happens to be standing near by. Would you push this fat person onto the tracks and kill him to stop the trolley in order to save the five? Nearly all who answered yes to the original problem answered no to this variation. But what's the difference? Isn't the outcome still the same? Sacrifice one to save five? It's still a "net gain" of four lives.
