An issue with this line of reasoning is that Darwinian evolution fails to accurately describe real evolutionary processes.
A counterexample is meiotic drive, where alleles disrupt the meiotic process in order to favour their own transmission, even if the alleles in question ultimately produce a less fit organism.
Whilst this is not an inherently positive observation, I think it does illustrate that the fatalistic picture you're painting here is incorrect. There's room for tentative optimism.

That is not correct. Darwin did make a mistake, but it was not the fundamental dynamics of the process, but that he chose the wrong unit of selection. Darwin thought that selection selected for individuals or species when in fact it selects for genes. Richard Dawkins is the person who figured this out, but Darwin knew nothing about genes (OoS was published only three years after Gregor Mendel's work) so he still gets the credit nothwithsanding this mistake.
