Yup - but doesn't make it right.
Execution is not only justified but required to prevent terrible crimes
Nope, execution is unjust and overhauling the penal/justice system to keep dangerous criminals separated from society prevents re-occurrence.
I would go for doing away with the death penalty if we sent all criminals to a remote prison in Alaska.
You are very wrong.
Your new order thinking is what is wrong with America and responsible for the deplorable state of affairs.
