Politician Sex Scandal: Who is correct?

I was reading an interesting story about this gentleman named Piero Marrazzo.

Marrazzo was the governor of Lazio, the Roman district of Italy.

Marrazzo was an admirable man but he also had lustful appetites and fondness of pleasure. This man frequented transexual prostitutes and took cocaine.

One day, a group of four gentlemen who worked in the government decided to secretly film him in his apartment in North Rome and what they filmed was quite a show. This group, led by Nicolas Testini and Carlo Tagliente, then approached Marrazzo and threatened him to leak the video of him with his whores and his cocaine use if he did not resign.

Needless to say, the man stepped down and he was greatly embarrassed.

However, Nicola and Carlo also got arrested for blackmailing a politician and also a charge on violating a persons privacy.

But who did the ethical thing over here?

Are we to say that Carlo and Nicola are unethical or are they simply men who were seeking to expose the truth to the people about their politicians. To show corruption and betrayal are very much real and not just hearsay.

Or is Marrazzo in the right? Even though he was a married man with children and not to mention, a powerful governor of Italy’s capital.
