Of course that is the pashut pshat in the pasuk. The Tanya is certainly not the simple and logic pshat.
So, I’m asking how he learns the פסוק.
Sechel Hayashar, I’m well aware of how stiros are answered. I don’t see how you are answering in way which fits the pasuk.
Essentially, you are reading it as follows:
(There are two types of tzadikim: those who don’t do aveiros, and those who do.) Of those tzadikim who do aveiros, none of them don’t do aveiros.
