>100% percent yes, for example: The absence of free will forces us to stop judging people, simply because the concept of "guilt" (on the negative side) and the concept of "merit" (on the positive side) are proven to be entirely baseless. If we applied this to our culture, we'd live in a totally different world.

Not really, it doesn't matter. If there's no "free will", then we have no say on whether we judge people or not, not even as to whether we believe in free will or no.

Your answer works accidentally on two conflicting levels, assuming that if we discovered that we have no free will we'd still have free will to act on a certain way upon it (not to mention that the discovery itself wouldn't be on our own free will).
