You told that some people might think that they are good, but can't they be mistaken ?
Lets be objective.
Cons:
1) All of them used people for their own desires (Can't say about Trinity, because I don't know much about them and don't want spoilers)
2) All of them spit on human freedom
So, they are just toying with people, treating them like slaves
Pros?:
1) "Artist" might gave protection to it's people, for the cost of their free will (because not many wants their hobby to become hard work), but... did it actually protects people ? If I'm not mistaken, the mist and trees growing caused by some demon, which you can kill ? But when you kill him, nothing changes ! So... could it be, not the demon, but the "Artist" causing all of that ? And he is not actually defended people, but imprisoned them ?
2) "Mother" obviously egoistic liar, that do anything to make people do what it wants. "Truth" is only a tool, a cake (if you played Portal you know what I mean), to make MC and Hana do what it wants. You could say, that some people might like to be all time horny ? I could say that strong feelings making people crazy and delusional. They are mistaken.
3) "Glaaku" used people for experiments, giving them knowledge that they probably don't want in a first place.
You could say this is neutral, but... it might used it's power to force people into all of that.
But also you could say, that these people are happy with what they are doing. Do you know what is delusion ? Kind of delusion, when human has no such desire in a first place, but for "some reason" it appears ? And I feel like divinities has such power, but also great brute and magical force.
So, even pros looks questionable, analyzing them with deep psychology and logic. And if someone likes to be deceived and used, then they are idiots or perverts.
