He was going to die eventually according to Daniel Lee , because of the brain transplant surgery, so why fake…
You should check out the last mouse special. He did got emotions after the surgery but he was also slowly turning into his previous self while he didn't remembered his past. And as he was faking in the early part of the series you can't rule out the possibility of him faking again
Why do I feel like JBR didn't die. HSJ told him that he had made plans so that both of them could escape the prison. So my theory is what if JBR didn't killed HSJ there and that was all his plan so that HSJ could leave the prison while everyone thinks he is dead. His prison guard friend was either fooled by him or either helped him out as JBR saved his fiance, so he simply repaid the favour. And in the end he simply acted out in front of OBY and KMC so that they believe he is on the deathbed and don't try to investigate much. I feel like JBR also faked his death to escape from the prison in the end too.
