In regards to the Chloroform interpretation, I think Mars is having a reaction to "eyes" discovering that he is "insecure" by poisoning the person with Chloroform, to make them forget what they've seen. Mars clearly wants to highlight on a bad guy kind of persona who doesn't care and is unmoving. He poisons whoever can see that it's perhaps an act, and he is actually in conflict with his self.
