Agreed with the first part of that.
The second part I'm less sure of. It may already have happened iff the world as it is is consistent with what we'd expect such an entity to create, which is precisely what I'm wondering about.
My instinct is to say "nonsense; it could certainly create a world where irrevocable suffering and death aren't quite so common, without violating that constraint"... a point that the Fun Theory Sequence also makes at some length, IIRC. But on thinking about it I'm not at all sure that it could without spoiling the scenario altogether.
For example: even in the world as it is, we are remarkably willing as a species to behave as though we were being taken care of by an all-powerful supernatural force; it might be that any significant further reduction in our suffering that wasn't visibly our own doing would bring us over a tipping point where that willingness became a literally irresistable temptation.
Dunno. It seems as though it ought to be possible to make more specific predictions based on that speculation, perhaps even falsifiable ones, but thus far I've failed to get traction.
(Another objection: it sounds more and more like the Christian take on the problem of evil, which is to say: fuck the deity that thinks it's best for us, we should take care of ourselves instead. Even if we should grow lazier and more complacent, real suffering has a higher moral cost than whatever qualities our life might lose.
Didn't most people here agree that the society of Brave New World, whatever its flaws and vices, is better than the current one?)
Foie gras, the delicacy made from the liver of a very fat goose (or sometimes duck), is believed to be unethical and is therefore frequently banned. For a long time, it was believed that the only way to properly fatten a goose is to continually force-feed it through a tube over several weeks, which is probably a highly unpleasant experience, although it's difficult to tell. Recently, Spanish farmer Eduardo Sousa revealed that under highly specific conditions, you can get geese to fatten themselves voluntarily.
Geese will instinctively gorge themselves when winter is coming on. Eat a goose right after it's fattened itself up for the winter, and you get a delicious treat that died happy. The problem is that geese will only do this if they believe food may become scarce during the winter (or their instinct to gorge only kicks in when the environment is such that that would be a reasonable inference; it's not clear whether it's the goose or evolution doing the analysis). If they realize that food will remain available during the winter, they eat normally. And there are quite a few possible clues--farmers trying to replicate Sousa's setup have discovered that cheating on any part leads to unfatted livers.
