There's an endless loop in this argument.
Per definition, if free will doesn't exist, then you can't say that "the illusion of the free will influences our lives more and in multiple ways."
If free will doesn't exist, then our lives, thoughts and choices are predetermined, and thus they can't be "influenced" by our belief in free will (or lack thereof).
In fact if we are in such a world, the we can't even opt to believe in free will or not -- since in such a world, our beliefs are also predetermined themselves.
The society wont be any more "compassionate, healthier and happy" in such a world based on any of its beliefs. It would only be compassionated, healthier and happy if its predetermined to be so.
The only option for your argument to work, would be for free will to exist while the society doesn't believe it does. Such a society, indeed, could be more compassionated, healthier and happy (it remains to be proven, but it's a possibility that non-belief in free will could change things positively, as long as free will exists for this non-belief to make a difference).
