I think you are all laboring under a false presumption:
"God likes to torture people/animals/whatev."
All the shadowboxing is a bit strange, but it's obvious enough that I'm not offended. I'm just curious where you're going with it.
Your thought experiment of God as a universal, amalicious, non-interceding set of rules did engage my brain in a good way. You're just describing natural reality, but in a way that superficially looks like the Christian god. Even, apparently, to a believer who thinks that suffering is a punishment for "communal sins".
This is simply not correct:
God created a universe that is capable of producing complex interactions, which lead to things like cancer; leads to diseases; and leads to adversities of various kinds. (it leads to such things, as a natural consequence of such things being POSSIBLE. EG, "metastatic cancer" is a consequence of the same mechanisms that drive evolution-- random mutation, caused by random chance.)
This is correct (supposing a creator god) but has no bearing on whether God enjoys torturing animals.
We don't know the creator's motivations. Curiosity or sadism or anything else. We can still judge the act of creation as disproving the omnibenevolence which many Abrahamic believers claim Jehovah has.
Again, think less "Crochety old bastard who hands down capricious and arbitrary restrictions/rules", and more "Superposition of all possible states."
God created a universe with maximum potential. This also means that there is a practically endless potential for maladies of every kind.
Humanizing a creator deity doesn't make much sense. However, it's still wrong to throw a dozen puppies down a well, even if one survives. Or, if done in an Earth-like computer simulation, one shouldn't expect one of the fraction of surviving simulacrums to look at the mountains of death and suffering on Earth and think "This is good." It could serve the creator's plan, but that does not make it good in the context of that world's inhabitants.
Your human-centric worldview likewise has you blinded to a terrible reality--
Human kind is the most destructive and terrible thing on the planet, and so far, has shown very little care or concern for others of its own kind, let alone other lifeforms on the planet.
We're the most powerful entities on the planet, but we only got here because we have incredible depths of compassion and empathy. We are social creatures, that is our greatest strength. Those who don't cooperate are excised... as a general rule.
The modern era has invented some rather rampant behaviors contrary to that.
