Remember, he's using the Lacanian / Zizekian definitions of terms, which are a lot different and more nuanced than their ordinary definitions, so you're probably the "good kind of sadist". ;) Lacan ironically classifies Marquis de Sade as a masochist!

From the extended paper:

Pervert, in the Lacanian definition, actually means a person who enjoys being a vessel of the rules. Zizek identifies the method of discourse that the psychoanalyst uses as the pervert’s discourse, because the analyst sits in the position of the object of desire for the hystericized subject. This means that the analysand [the person being analyzed] projects their ideals onto the analyst during a process of questioning known as transference. When we use analysis to determine why we use a programming language, we are operating in the analyst's discourse. It is important to have a basic understanding of Lacan’s terms (such as perversion) in order to understand the cultural critiques of Slavoj Zizek and other Lacanians.

“Thus, in psychoanalysis "perversion" is not a derogatory term, used to stigmatize people for engaging in sexual behaviors different from the "norm."”, Bruce Fink. A Clinical Introduction to Lacanian Psychoanalysis: Theory and Technique (Kindle Locations 2460-2461). Kindle Edition.

“The Other's desire or will is accepted by the masochist instead of the law, in place of the law, in the absence of the law. As Lacan mentions, the Marquis de Sade (better known as a sadist, but in this instance manifesting decidedly masochistic tendencies) pushes his mother-in-law, Madame de Montreuil, to the point where she expresses her will that Sade be punished. It is her desire or will that has to serve Sade as a law. Not the law, but a law.”, Bruce Fink. A Clinical Introduction to Lacanian Psychoanalysis: Theory and Technique (Kindle Locations 2805-2808).
