No, not at first. Casso and Amuso were only out to get everyone identified as an informant. They were trying to clean house to fortify the Lucchese operation against the rest of the federal government. But eventually, Casso, Amuso and the Geminis would have to decide who would be the victor, as there is no honor among thieves.
Didn't Amuso and Casso eventually have a falling out during the time of their incarceration? I rest my case.
The real question is: Who would have come out on top?
Did they really end up getting transported in a prison van together at one point? In Carlo's book, it said that they ended up being transported together by coincidence and Amuso told Casso something like "I bet you regret ratting".
