I can’t say for certain not having read those books, but in general Star Wars does present the Dark Side as something evil and its adherents as villains who aren’t to be emulated (does anyone really want to live the life of Palpatine or Vader? Look closer at what that entails - constant backstabbing and paranoia, disfigurement, being burned to a crisp and having to rely on a life-support suit just to breathe, committing numerous war crimes and crimes against humanity, being rubbish at actually ruling a galaxy-wide empire, an aversion to sand, etc. etc. etc. – for anyone who said “yes”…) so in that light it would be OK.
If it were to present the Dark Side as something actually desirable, then it’d be iffy IMO.
