There is no original manuscript for the bible, and we aren't discussing this in ancient Hebrew. Therefore, to say there is no chance for misinterpretion doesn't really hold water. However, this is hardly my area of expertise so I won't argue the point any further. Besides, I think we are all in agreement with the sentiment I meant to get across, which is that hitting children is bad.
Also, any of it can be justified as character flaw. Even if Protagonist was a certified theologist, he might bend truth to his own advantage; and let's be honest, it wouldn't be the first nor last instance of it.
Also also, maybe in their world bible is slightly different. You know, alternative reality and such. And even if not imagine thinking about biblical accuracy in a game with that amount of taking liberties.
