Would you rather escort a group of civilians to a known safe location from a ruthless invading force saving them but leaving your close comrades behind to face the enemy without you and live with the guilt if they failed - or would you rather stay with your comrades and fight off the enemy with honor and a high chance for victory while leaving the people to flee for themselves, defenseless, unorganised, and likely to meet certain death?
