User blog comment:- Darkchylde/Alluka as Nen exorcist/@comment-4896558-20150727021718

Personally I think Abengane was successful or rather in a sense I hope he was, since after writing his summary Abengane. His Nen ability mentions that either a snake or devil will appear from the ritual campfire he makes and it will exorcise the imposed Nen. So since a snake came out of the fire, which could represent by means of selfish goals for example and ate the Bomb attached to Abengane's shoulder. The devil could be by means of hatred or ill will. And if Togashi ever starts doing the manga again, I bet he'll bring back Abengane possibly as one of the new Troupe members and shows off the Devil Nen Beast he had to conjure in order to exorcise the Chain Jail from Chrollo's heart. But it's all just hypothetical to be honest.
