I totally understand all of this about the joke. I understand Tom Hank's character is meant to be the villain.
The author drew this. He thought the world needed it. The objectification of woman is part of the punchline. This is why it's punching down: The author used the objectification of woman (a real problem that woman experience in their life) to serve the punchline. It makes no real critique of the male character here, it simply presents him and his actions. Can you have bad characters in a non-problematic comic? Yes. Is this happening here? I'd argue no, because a misogynist can just as easily laugh at this comic for misogynist reasons.
I'm just pointing out the comic is gross. If you found it funny I don't think you're a bad person. I just don't think it deserves to be here without someone complaining (which I am doing).
