I mean, I can guess at your objection - it was a different era, the people involved in these murders were ordinary churchgoers rather than leaders, etc. But none of those caveats address the issue at hand: your claim (and WLC's claim) that if an order comes from god, it's good. Period. Well, these people claim to have been ordered by god to kill their children, either directly or by proxy. Were they moral acts? It's not a trick question, nor should it be difficult for you to answer.
