Ultimatum

What would you do if you found out that it was someone's last day to live?
A complete stranger. Someone you have never seen before.
Would you do everything in your power to save them. To break the path they are on and to give their family back their child/siblingz etc. they would have lost. All the while not caring what reprocussions such an act would bring for you and for this person whose life was supposed to end.
Or
Would you have the faith and the courage to stand there and realize that everything in life has it's purpose. That even though someone's child lost their life soo soon that maybe, just maybe, it may have been needed in some way.
This is an extremely tough question I have been pondering.
On the one hand you have someone whose life is going to be cut short suddenly and often times tragically. Yes, the family would be spared of their pain of losing someone soo dear and have more time with their loved one.... but what is the cost?
On the other hand you, given this knowledge, would knowingly let this person die. But you would hold on and then see the lingering effect this person had. Sometimes on more lives after death than during life. This person's loss of life could be the key to saving many more.
So this is where your choice comes in...
Save Them or Let Them Go?
