HEY I LIKE BEAT ;_; I don't think Joshua is loveless, just that he's not loving, if that makes any sense. So the way I play Joshua, he has conflicted feelings about bringing back Rhyme (moreso than Beat) - he justifies bringing back back Beat, Neku and Shiki to himself because none of them really 'lost' the Game - Shiki actually won, technically, but Kitaniji couldn't revive her himself, so that's his excuse for her. As for Neku and Beat, the third week was clearly breaking all sorts of rules, and even if it wasn't both of them still reached the endgame unerased. Yes, there was that thing at the end with the gun, but that doesn't really count as a proper Game. Rhyme, however, lost fair and square and the fact that he brought her back means that he's getting too close to humans to dole out unbiased judgements.

So yes, I agree that he's not a heartless monster, but I think that he was getting dangerously close to it before the long Game and before Neku. Say what you will about justification, but the guy was about to destroy an entire city. That is not something a good guy does. And Joshua (my Joshua, at least) is not an omniscient god, he's just a human who was gifted with powers and uncanny wisdom - I don't think he was doing it out of love for mankind so much as pure frustration that they weren't turning out to be what he wanted them to be. The way I play him, Joshua does his incredibly irritating, unhelpful, cryptic best to push people to open up their worlds, but if they don't? He's not going to help them any more than that, he'll just watch them die with no emotion or regrets whatsoever.

And again, I haven't seen any of this RP, so you may be right about his interactions with Hanekoma. But I think that if Joshua is going to be petty and childish with anyone (in a serious manner, not just to purposefully annoy them), it would be Hanekoma, the only person who ever actually knew him as a child.
