Your comment boils down to, “McBride made some bad choices, and bad choices have consequences.” Okay, Wafer made a really bad choice as well. He opened his solid, safer front door and pointed a gun at the person standing on the porch (through the much less safe screen door) instead of calling the police. So Wafer made some really bad choices, and bad choices have consequences. In this case the consequences should be going to prison for manslaughter. Both McBride and Wafer should have equal chances to recover from or face the consequences of their mistakes.
