This "fantasy" book series is where ethical values and Universal Human Rights go to die. The basic premise of this fantasy book series is that humans are enslaved to a "superior species" and used for forced work, forced breeding and forced gladiator style fighting. Is it promotion of slavery, continuous sexual assaults, and forced labor? Yes! Is this "ethically skewed"? Yes!
If extrapolated, do humans treat horses, cows, chickens, dogs, cats, etc. animals in this manner as well?? Yes!
If you can overcome the continuous sexual assaults, the intense sexual descriptions, and the idea of "breeding" humans as if they were farm animals/Breed Horses, etc. then the story seems organized and even though it's another "reset"/second chance at life (undo the wrongs of first life) book series, this main character, doesn't really stop slavery, undo all the wrongs, create a legal system to stop all of these crimes, and just benefits, creating his own team of humans, his own harem of enslaved women that were used for "breeding", etc.
So, yes, I think author and story has little to no Emotional Intelligence as well. The cover, doesn't really have any relation to the story itself. There are no maps inside, no inside illustrations, no character summaries, there is world building with geopolitical, economic, social system descriptions of this "alternate reality world where humans are treated as slave/pets". A kind of Planet of the Apes, but with "aliens" that aren't humanoid.
