Tarrlok has to live his entire life without bending now.This much bigger punishment than the death.
Plus Amon is way more dangerous.

^Excellent points.

I really don't want either to die.. and I just like Amon too much.

' And Amon saves day' i was saying that when tarlok was confronted by Amon

Why should they die. They will not pay for the crimes they done. They just may welcome death. Tarlok bending should be token away. Both should be forced to spend the rest of there years in prison

Tarlok isn't the big threat here bloodbending can be over power but Amon can take away someone's bending dewndling and the world needs bender's so Amon

tarlok now is nothing
