Agree - but many Christians don't live with a Kingdom vision (Romans 12:2).
Many have the idea that morality is strictly personal preference, and not a bedrock truth.
The Bible defines the nature of truth - because all things were created by a single divine mind, (“In the beginning God created…” Genesis 1:1), all truth forms a single, mutually consistent system. Truth is unified and universal. Not personal preference.
Yes, I still sin, but the premeditated taking of a human life? In the face of both scientific and Biblical truth?
I like your tagline; but those guys were TRAINED; premeditated you might say; to take human life.
