There have been teens that have killed little babies, and yes they should be given the death penalty. Being a minor is no excuse to be allowed to rape and murder in cold blood.
We are talking about sex offenses here.
So you want the death penalty for underage sex?
Sounds kind of extreme to me.
You are the one that said that, "A second offence even without killing the victim should result in the death penalty." So back up and think for a second. All sex offenders are not created equally.
