Interesting point. I think you're right; they probably did figure that the guy had no choice - for all the big talk about Omerta and "our thing" and keeping quiet, 30 years isn't something to scoff at. I'm willing to bet that's why they gave him such a dignified death instead of just whacking him like any other mook a la Jimmy Altieri (who was a Capo himself, I don't recall if Pussy was actually a capo or just a button man), because they knew he he had no choice. Neither did they in killing him, which is why Pussy relegated himself to his fate.
