He starts off kindly enough with this thought.
Yes, Ophelia is divided from herself and her judgment. She is disassociative and outside her own norm.
But then he kicks her while she’s down – calling her a picture and a beast. Not directly, of course – but he first says she’s divided from her judgment and adds that people without judgment are pictures or animals. Ipso facto and so on.
Pictures is funny, though. We are pictures without judgment? Pictures?! Pictures are an awfully static analogy for a person without their judgment.
A person without judgment may be many things – but still as a picture is not one of them. A beast, I can see. That analogy makes sense. Maybe what that last sentence is about is Claudius choosing the better analogy. And he settles on the same one Hamlet found for man if his chief nature be but to sleep and feed.
