Now this doesn't necessarily mean that Rocco was lying here. Also, just because he says it's difficult, but not impossible, it doesn't mean he's at this moment volunteering for the hit. He is just answering a question: is killing Roth possible? If he said, "I think I can do it myself," that would be different. But to infer that Rocco's statement was meant as self-enlistment for the hit is a stretch. Again, he's only answering a question, and as Turnbull observes there was only one answer he could give, whether that answer was his true opinion or not.
Rocco was not responding to a hypothetical or impersonal question about whether or not Roth could be killed. Nor was he thinking that perhaps someone else could be engaged to do the killing. The operative premise--the one that set off Tom's reply and Michael's humiliation of Tom--was "I want it [Roth's plane] met." Michael said, "Rocco?" Rocco had to know that Michael intended him to meet the plane. I think you're having difficulty believing that anyone would "volunteer" for what seemed certain to be a suicide mission. You and I wouldn't, but you and I aren't Rocco--a guy who had been brought along by Clemenza in the ways of old-time Mafia obedience; who was losing status in the family to Neri; who was put on the spot by his boss after the boss thoroughly humiliated his "brother"; and who may have seen (or rationalized) in this mission a glimmer of a chance to get away with it and reinstate himself in Michael's estimation.
