Hummmm. Depends what the crime being punished is. I'm guessing you're not too bothered about sins against God?
I think you've missed the point on proportionality.

Whatever sins may have been committed against God they are finite, yet God's punishment of those crimes are infinite. God is not just by any common meaning of the word - no one would consider being burnt alive for an infinite period of time to be a proportional fair punishment for any crime. In this way we can say that the Evangelical god is not just.
