Tt appears to be a pretty sound review of evidence, and then a discussion and conclusions section where the results of the review are interpreted and implications are discussed. Seeing "sad" appear in an abstract is sort of unusual. However in the discussion in the review the arguments about morality etc are a bit more sophisticated, but I reckon it isn't too odd to have a value claim on the implications of the review being unfortunate, since they have real implications for human wellbeing. If the same sentiment was couched in normal amounts of academic jargon, you would likely not have noticed.
