Especially as we know he was friends with Gangle and he knew Kinger and Ragatha before Jax
If Kaufmo had abstracted soon after Ribbit, I'd agree that Jax deserves the blame and we should hold him responsible since he pushed Kaufmo away and dismissed him. But since he didn't, I don't get the idea Jax is the one who drove him to abstraction as he had other friends than Jax and Ribbit. It was despair at realizing he'd forever be trapped there and thanks to Caine's fake exit that he likely conjured. Not to mention, we literally know the other's didn't laugh at his jokes either, they're not as guilty as Jax but that almost certainly played a part. IMO the guilt goes Caine > Jax > rest of the circus members than just Jax.
