He’s a Kaleesh that was transformed into a cyborg. Pretty much the only parts that remain of his original body are his eyes, brain, and the rest of his organs.OK. Basically another Vader with more stuff damaged/replaced. Since the lung obviously doesn’t work properly either, I would have replaced that as well.
If the lung itself is the force bearer that might be the reason to keep it.
Silly, but… well.
He’s not force sensitive, so that’s a good point. It’s clear the lung wasn’t working correctly, so they should’ve replaced it.
After they got done operating on him the first time and wheeled him in front of a mirror, he probably decided then and there to avoid any more surgical procedures at all costs.
