I cant say it would easily be the 100 complete strangers, but I know I would have to pick the 100 strangers either way. Sure its easy to say that the 10 people closer to me are more important to my life than 100 strangers, but then what about those 100 strangers? How many brothers and sisters, mothers and fathers, sons and daughters...how many of them would have to suffer because of my selfish decision to keep those I love and cherish alive? How many of them would have to live without their cherished ones around while I still had mine?
Then there's the fact that I know many of the 10 people I am closest to would never forgive me for choosin them over 100 others. The blood of 100 people would be on not only my hands, but their hands as well. The 100 random strangers I may never see again and all they'll know is that someone saved their lives, the 10 people closest to me will always know that I killed 100 people...I choose to end the lives of 100 friends, family, loved ones all for my own selfish desires.
It'd be painful and I'd have to metaphorically rip my heart out to do it, but really...the only option for me would be the strangers.
