We no longer have a trope called Spectacled Sadist. You may be looking for one of the following:
- Four Eyes, Zero Soul - Showing that a character is cold, cruel or ruthless by giving them glasses.
- Kichiku Megane - A fanspeak term for a Fetishized Abuser Love Interest with Stoic Spectacles or whose Glasses Are Sexy.
If you came here from a wikilink, please go back and correct it to point to the right trope. You may also be interested in the other Glasses Tropes.
