Unless you have any support for these hypothetical questions,
I don't know what you mean by support. Doesn't your whole argument hinge on our support being completely divorced from objective morals? Like if I disagree with objective morality objective morality wins right?
Anyway a hypothetical situation is just that. It isn't an argument for how the world is or should be but designed specifically as a thought exercise. The whole point is to see if you can agree with "true meaning" and "objective morality" if you find them horrible.
I think if you examine your (subjective personal opinions about) morality you will disagree with any god(s) whose moral pronouncements differ too drastically from your personal moral intuition.
I have every right not to take them seriously, I don’t know.
You are under no obligation to take anything I say or suggest seriously. Indeed it is not meant to be taken seriously exactly. I'm not seriously suggesting such a figure actually exists. In fact I don't believe in a god with moral pronouncements the polar opposite of your moral intuition any more than I believe in one whose more intuition matched yours. Yes I would say I think those two prospects are equally unlikely. The point is just to see this from a different perspective. To maybe get some insight that is hard to see unless you look at things from a different point of view.
I can answer this question. If any god(s) exists and if they disagree with me about what constitutes morally correct (human wellbeing is "good"), especially if I consider their morality particularly egregious (pointless and preventable human suffering is "good") I would not change my perspective. I would have the same reaction based on their actions and moral pronouncements. I am self accountable for my own moral integrity even under your model.
