Killing vs Murder; Conversing w/Mark

What should be a Christian's position on murder and its punishment? In this second episode where I converse with my old friend Mark, we work through the biblical framing on killing vs murder. Is the New Testament full of mercy whereas the Old Testament was full of vengeance? Were there two different Gods, and Jesus brought with him news of a loving God? Do most people live according to love or fear? Why? Why is an appropriate level of fear not only helpful but necessary for society to flourish? Or, here's a hard question: is the anti-capital-punishment church of today more wise and/or virtuous than the church of seventeen hundred years? More locally, how did the recent plea bargain deal offered to the Moscow murderer play here in Idaho? How'd that plea bargain play with some of the family members of the murdered? Let's think through this difficult topic from a biblical angle. Come laugh and think with myself and Mark.
