if it was for a group of people, id die for my family, but if it was my life in exchange for another, theres no-one yet that id exchange my life for.
but in heirarchy of an individual loved one, for example my brother
if i had to sacrifice myself a quick death to save my bro from a quick death- wouldn tdo it
if my brother was gunna get tortured and a long painful death, and i could stop it with a quick death - id do it
if my brother was gunan get tortured and i had to be tortured to save him- wouldnt do it
