Ah, the wants to break the legalism they must adhere to versus the murderous wants of a doctor, thus born the desire to "accidentally off" the Prof. Yet it is in the dream-scene where the Prof walks away is where the Prof has finally been "offed" and the desire has finally been lived through in the Doc's Unconscious state. Thus, he can be at ease to finally have the satisfaction and the want to exact those grudges, even if consciously he knows the Prof walks away scot-free. Upvot'd and resteem'd.
This is deep and a very interesting comment. I'm not even sure how to respond others than, WoW.
I like your take away and perspective on this.
