Personally - I would recommend some of the books as well because they are incredibly prevalent in the American psyche in some form or another.
That is not to say that I endorse their methodologies. After all - win friends is impossible for me because if its basic premise “you must be genuinely interested”. I’m rarely ever genuinely interested in anyone - as most people I meet are pretty terrible individuals. (Maybe that’s just a side effect of living in cutthroat SV)
There are many reasons that even ordinary people should, in my opinion, read such material and take it in, but the most important one is that understanding how other people work is necessary to knowing if you are being manipulated and how to out-manipulate the manipulator if that's called for.
Of course, I think if I didn't include the 48 Laws of Power, attributions of sociopathy towards me (yours certainly not being the first) would be largely diminished. Cialdini's books, if you were to read them, certainly aren't written as guides on how to be a sociopath, but rather the contrary. The 48 Laws of Power is written the way it was to be the most entertaining and thematic, which I think is pretty clear.
Most evil of the psychopathic nature are conducted by people nearer to the psychopathic end of the spectrum but they aren't quite totally psychopathic. They bridge that gap by justifying their actions with lies they tell themselves.
Hitler, for example was unlikely to be a psychopath, but the actions he committed makes it seem like he was one. He was also likely on the far end of the spectrum in terms of psychopathy and clearly he still had some story he used to justify his horrific actions.
