We no longer have a trope called Spectacled Sadist. You may be looking for one of the following:

* FourEyesZeroSoul - Showing that a character is cold, cruel or ruthless by giving them glasses.
* BespectacledBastardBoyfriend - A [[RomanticizedAbuse Romantic Abuser]] LoveInterest with SexySpectacles or StoicSpectacles.

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 GlassesTropes.
