Now, here's where its cloudy for me. Was the killing of Tattaglia, Stracci (sp?), and Cuneo just to prevent them from coming after the Corleones for killing Barzini, or was it something else???
If I'm not mistaken, only Barzini, Tattaglia and Moe Green were killed in the novel. Tattaglia was killed as further payback for Sonny's death (despite the fact that Tattaglia's son was already killed). Moe Green was killed because of the way he handled Fredo and Barzini was killed to stop the threat against the Corleones.
I could only suggest the others were killed to juice up the movie.
