The worth of losing lives to save the majority is a interesting topic and can be seen many times throughout history as seen in really any mas killing through out the world, this I would say might be worth it and it depends on the circumstances that have happened such as if millions of people were dying due to one person then yes that person should be killed but if it is about an equal amount of people on both sides then no because yes you think that they should be killed but on the other side they all that you all should die so it would be about equal if one side was killed.
