"What causes happiness in individuals is subjective.... This is choice. This is free will."
I may be able to accept a position like this, but I would need to see it substantiated and supported. I would need to see that it was consistent with other aspects of the worldview. This thread is asking about free will from an atheist's point of view. Atheists nowadays almost universally believe that evolution is actual history. Do you?
I will draw the point right away, assuming a 'yes' answer. Given evolution, what causes happiness may very well be subjective, but it doesn't follow that your choice to choose happiness is done freely. In fact, doesn't it follow that if we are the product of evolution, every aspect of each of us- subjective or not- is the result of selection processes, whereby each decision has the goal of furthering our own survival long enough to successfully reproduce? Within a world where evolution is real, shouldn't it follow that 'happiness' itself is an evolutionarily derived state that either contributes to or is synonymous to survival and reproduction, and so a determined thing?
What you are calling choice may very well just be instinct, right?
"There is no way to determine whether this choice was preordained or predestined and I really have no control over the matter. We appear to have free will, and no one can prove otherwise."
So you believe we have free will based on faith?
"We may all be part of some vast VR network and controlled by little kids playing a SIM game, but we are not aware of it. It doesn't effect our lives in any meaningful way whatsoever, as far as we can see. So it is useless and not productive to theorize about it."
Sure, there is always solipsism. But not all solipsistic (eh?) possibilities are created equal. A 'VR network' 'controlled by little kids playing a SIM game' strikes me as implausible. A VR network controlled by folks at Microsoft as strikely more plausible. Whoever is in charge, they've done an awfully darn good of instilling in us a pretty darn good illusion, don't you think? Might the quality of the illusion we experience somehow proportionally speak to the abilities of the entity that sustains it?
Couldn't free will itself be evidence of their existence?
I happen to think we may even be able to determine a way or two to test the particular scenario you gave us.
I am shocked, shocked, I say, that you would not want an explanation for this reality in your world.
"1. Do you think anyone is genuinely happy oppressing people?"
I thought you just said it was subjective. We must allow for the possibility.
"2. How long do you think you could oppress people before someone revolts and kills you?"
Excellent. You have now retreated to an evolutionary point of view. Well, you've made your bed, now you've got to lie in it. Consistent with this view, you need to agree that your 'will to happiness' is at best only a result of a survival mechanism or the survival mechanism itself. Ie, its not free will. Its determined by your brain chemistry and the long history of evolution leading up to this point.
However, that means if someone were to be happy oppressing people, this would only be another evolutionarily derived point of view. Given that the history of humanity is filled with oppressing people, I can only imagine that the answer is "yes, some people are happy oppressing others."
We can oppose them, apparently, on survival grounds- both parties are not representing free willed choice- but not on moral grounds. Because moral responsibility ultimately requires that there is a free choice and a person could have done otherwise.
