Now Im going to ask you this:
Whould you kill your baby girl knowing if not done so you would doom the Universe?
Like I said they made their choice like humans, like individuals. Did not Scorch sed " Sir, we cant just leave him behind " ,and "What do you mean one soldier, he was my pod brother!". In the end he understood why, but he felt the loss. A soulless man would just continue to obey the orders with no emotions.
They are ALIVE.
By the way who knows, we are too far away and far too late to understand them.
May the Force wach their souls.
"YOU MUST DIE, I ALONE AM' BEST"
