See other replies to your parent comment for other ways of phrasing that free will as it relates to ethics is generally deemed a moot consideration. That is, we can't predict the future from our perspective of reality (computationally prohibitive, non-deterministic, etc), so what the future will be can’t be taken into consideration for decisions of the present. To me, your concern seems more related to the meaning of life rather than the presence of free will though? Unfortunately, I fear that’s may be too broad a subject to fruitfully assess on a medium such as this forum.. At the least, I’d argue ‘you’ existing is the only thing you can really be sure of. “I think, therefore I am”. It’s harder to tell if others exist, and there are several branches of philosophy that outright conject that nobody else other than yourself does exist.
