You nailed it.
Sacrifice is not always bad and in my opinion I think we could incorporate it into our culture today and see good. This going to euthanasia and the question of how much is life worth?
Is it worth it for a family to go into $100,000 in debt to keep alive a nearly brain dead family member? Not even remotely, but people do it every day.
Think of how much it costs for the elderly to survive with around the clock care. Now, if these people were fruitful members of society and are able to cover their own costs then it is of no consequence. But the situation turns muddy when many of these older individuals are disabled, not self-aware, and have not a dime to their name. Is it really doing anyone good to keep them alive? Not really.
I am not necessarily advocating murder, but imagine if it was in our culture for most people to have an advanced directive to take care of this wasteful case. Less financial drain on the system and for nearly no cost. This sort of advanced directive could be seen as admirable.
