The cost of life

I think that the cost of life is left to the person responsible for everyone. On the ship Titanic the captain is responsible for all the lives of those people who died because of the iceberg hitting the huge "unsinkable" ship or like in the call of the wild, Spitz is responsible for buck because its his sled dog so he has to watch out for him and take care of him. If you had to be responsible for peoples lives would you do the best for them?? that is the question.
