I don't even wanna give oxygen to such a ridiculous proposition. Paul Castellano was many things, some good, some bad, but no way on God's green earth would he have ever turned informant. No way! No how!

Whatever else he might have been, Paul was Cosa Nostra to the core. His father, grandfather, and uncles before him were. And so was he! He came from a long line of proud mafiosi.
