A Man of Honor doesn't go and tell just anyone
"I am a man of honor",shows its hidden power behind you and you must feel my weight when I get close to you, you must feel it subtly.
I don't come with a threat but I will always come smiling and you knows that behind that smile there is a threat hanging over her head.
I won't come and tell "I will do this to you", no, if you understands me, well, if she doesn't understand me you will suffer the consequences.

Tommaso Buscetta
Many say that Buscetta is a traitor, others that he is a hero because he demonstrated to the world the existence of Cosa Nostra, the real criminal organization not the mafia on the newspapers.
In reality he is just a man who grew up with values that turned out to be anachronistic, a man who, as was accused by Riina of having too many women, too many wives, "loved women but not power" while Riina went to bed with a single woman for the rest he just wanted power, he wanted to command the Cosa Nostra.
He is not even a nice person (he abandoned his sons to their fate) but he was also betrayed by his best friend Pippo Calò who was his boss but bowed to the ruthless Corleonesi and killed one of the sons. In 1984 Don Masino was a finished man who had two choices, both definitive: either wait to be killed or collaborate and renounce what he had always believed in.
Rome, 1984.
Months after his capture in Sao Paulo, Brazil, Tommaso Buscetta was extradited to Rome. He is tired of persecutions and massacres, he fears for his wife and children: the Corleonesi have already killed sixteen of his relatives. Thus, the "boss of two worlds" finally decides to speak. For 24 weeks, for 12, 14 hours of interrogation a day, Buscetta remained locked in a small armored apartment, talking to judge Giovanni Falcone. He tells him what the criminal organization he is part of, he explains to him what it means to be "men of honor". And he mentions the name that from then on will forever replace the journalistic name of "mafia": Cosa Nostra

“To become a man of honor one must take an oath in front of five or six family members:
the... candidate, let's say, is taken to an isolated place, often to someone's house. At that point the eldest among those present tells him a series of things: that the purpose of Cosa Nostra is to protect the weakest and eliminate the oppressors..." Falcone holds back a smile. She frowns, and it's the only expression Buscetta can make out on her face. The "boss of the two worlds" likes Judge Falcone. Strange but true. It reminds him of the protagonist of a Pietro Germi movie on the mafia seen many years ago, In the Name of the Law: a young magistrate from Palermo, Guido Schiavi, who investigates a chain of mafia murders, managing to make the law of the State prevail over that of men of honor.

In Buscetta, Falcone inspires an unexpected sense of security: his shy air, his slightly shy character, never exuberant, never bordering on disrespect, make him think of the quiet strength of justice. Here, this is the concept he reflects on as he stares into Falcone's eyes, the calm force of justice. In Germi's Sicilian Far the local mafia boss, Turi Passalacqua, was convinced by the young magistrate to submit to justice. Which is exactly what's happening with him. That Don Masino is not a saint, despite this, is clear to everyone.
You can even notice it in his movements, in how he sits, in how he looks around. His isn't clumsiness: it's slowness. A thoughtful slowness, studied in detail. It gives him the opportunity to evaluate. Buscetta is someone who reflects and evaluates well before speaking. When Falcone saw him enter the interrogation room with his calm step - the air of someone who had no urgency, because he was the one holding the scepter in his hand - he knew he was facing a merchant. Of drugs or information, nothing changes.Not that this makes him a disloyal man. Every trade has its laws, even the black market, where everything is based on trust. There are no safeguards, no safety net for those who break the rules. No second chances. Trust is everything. Even now, Buscetta is applying the rules of the black market, the only ones he knows. If Falcone wants to keep him on his side, he has to get on his side.
“And then what happens?”
“He gets his finger pricked with a pin. The blood is dropped on a sacred image, then the image is held in the hand and burned, like this.”
Buscetta mimes a man holding something hot in his hand. “The candidate must endure the fire by passing the sacred image from one hand to the other until the fire goes out.”
“And is anything said during this oath?”
"Yes, certainly. The new affiliate swears to remain faithful to the principles of Cosa Nostra by solemnly declaring: 'May my flesh burn like this sacred effigy if I am not faithful to this oath.' Once the oath is finished, only afterwards, the man of honor is presented to the head of the family.
Also because there is this rule that a man of honor can speak to another only after having been introduced to him by a third man of honor known to both, a kind of guarantor... one who must guarantee both on the status of the other, is it clear? That is, trust is always risky in certain situations. We need guarantees.” Trust, always trust. Falcone writes down everything with his round and tidy handwriting. He moves his gaze between the notepad and Buscetta, who speaks solemnly. He tries to give as much weight as possible to his words, to sell the heaviest goods he has. As long as this trade doesn't damage it more than necessary. As long as his arrows don't take a wrong turn and backfire on him. “What is required of a man of honor? There is evidence, some...” “The most important thing the man of honor must do is become a killer.”
They glance at each other. Buscetta was also a man of honor, so he too observed the rules imposed on affiliates. All of them, none excluded. But this is a commodity excluded from the sale.
Every man of honor, before becoming a member, must have killed at least once on behalf of Cosa Nostra. He may not even know that he is doing it on behalf of the family, perhaps he believes he has done it on behalf of a friend ... "
" Is the affiliation permanent? Can it end or does it last forever?”
“Once a person becomes a man of honor, he is one for life. I have never known a case in which a man of honor went to his head of family and said: 'I no longer want to be part of Cosa Nostra.'

If a man of honor is arrested, it doesn't change anything, he's still part of the family: even inside prison he is always a man of honor, his authority is always the same. Then it can happen that personal life... something can happen that prevents him from being active, from participating in family things, this can happen. But anyway, whenever he is needed, wherever he is, he can be asked to do something. And he can never refuse. If you are asking me if a man of honor can spontaneously abandon his family... No, this can never happen.
