Especially since Hitler himself was Christian. As were frankly almost all medieval European rulers. Christianity has never stopped war (or suffering within wars) and in fact fueled a lot of it.
The fact that some general would make a justification like this is terrifying. If he genuinely thinks this would stop wars or suffering, he's blatantly uneducated. The other option is that he knows what he's saying is bullshit and it's just meant to convince the Christian population, which says terrible things about both how the military is run and how gullible that population is
I actually think that ChatGPT could eventually become the way to play tabletop RPGs. It's not quite there yet, though. It's not the most creative writer, still often has internal consistency flaws, and of course it would have to be trained specifically on the rules of the RPG you're playing. But once it has been, it could probably act as a DM for groups that lack one. Or as a very closely coupled assistant to less experienced DMs who may need hand holding. It could even likely replace players, which could be useful for solo players who can't find a group (or, say, have incompatible scheduling).
Unlike a regular video game, the format of tabletop RPGs seems perfect for our current rudimentary AIs and the constraints are ones that they can probably handle with careful training alone. It's also a useful niche since there's no replacing the open endedness of tabletop RPGs with current technology. There's also a lot of people out there that I'm sure would like to play tabletop RPGs but just lack a group. Anyone who's played them before knows that scheduling is really hard and has killed a lot of groups. That's something an AI could help with.
