What would Elrond do?
if you were lord elrond and you were in mount doom with isildur, would you kill him when he refused to throw the ring into the fiery chasm from whence it came?
remember, the race of men already shown weakness against the rings of power (ie. the ringwraiths), what more could they do against the will of the one ring... and the fate of the peoples of middle earth depended upon the destruction of the one ring...
i woulda chopped his head of so quick, put the ring in his pocket then throw his body with the one ring into the fires of mount doom...
what would you do? 😕
