William,
I would agree with you!

One of the straw-man arguments put against those of us who are Christian and favor the death penalty is that we are against justice. "What of those on death row who are innocent?", they claim. "Don't you have compassion?"

Most assuredly we do. In fact, there would be no greater injustice than for somebody to lose their life for a crime they did not commit. We, as Christians, understand this better than any, as our faith is grounded in an innocent Savior who bore the sins of the world yet who was himself sinless. Hence we want fair and appropriate justice, an honest legal system.

Grace is not common.
