I'll admit that at one point, I thought that Bonanno hated Luciano.
As per the War of the Godfathers, Bonanno funneled damaging information about Luciano to Dewey, which helped convict him. Bonanno even schooled the prostitutes how to lie on the stand. With Luciano out of the way, Bonanno would be able to be recognized as the most powerful don.
Afterward I found out The War of the Godfathers was a fictional book and I felt like an idiot for believing it was a true story.
