>Or we should think the fucker didn't gave a fuck about Nayuta security and let himself get fucked in the ass knowing he is immortal?
It was more self-loathing on his part. He told Nayuta that she shouldn't be around someone like him. He wanted to just irresponsibly live out his sadomasochistic fantasies as Chainsaw Man (which Nayuta admits she can't understand when she fights the human mob) and didn't expect Nayuta to stick around.
There is a bit of a parallel drawn between Yoru and Denji during that arc, and it's no surprise they later end up together as a toxic pair.
Won't surprise me to see if we see Denji going berserk again, soon. At the bottom of it he's an unhinged schizo trying to cling onto some semblance of sanity.
