and also I feel like his outbursts are 'be really edgy, make everyone hate you' and not how he actually is on the inside, which is mostly just grumpy and tired and done with everything.

Oh yes, true, good point. It's mostly about pushing people away. (Kind of like his grumpy demeanour in the early part of the drama, I think.)

He even overrode genetics entirely (looking exactly the same no matter who his biological relatives are, which I don't think is ever the case for other people who reincarnate), so definitely more god than not god. :D

*continues to be extremely baffled* (I should just stop trying to make it make sense, shouldn't I? ;-)
