I can agree with this in the scope of eternity, and eternal destination. Where I diverge is in the earthly realm. Sin is sin, and all deserve Hell for it. However, while stealing an $.80 candy bar is enough to send you to Hell, it will not get you 45 years to life. On earth, we have a scaling punishment system. Even as parents we do the same thing with our children. You stayed out 5 minutes past curfew? You might get grouned for a while. You went out with your friends and got drunk? You're probably going to get something more than grounded, and not be able to hang out with those friends.
This being said, that's why I believe the death penalty is appropriate for some crimes. If you destroy a (earthly) innocent life, then your life is no longer (earthly) innocent, and is forfeit.
