Members of the mafia are objectively as happy as the Sisters of Charity?

Depends. A mobster derives happiness from money, beating up his enemies and having sex with attractive women (among other things). If a mobster gets enough of these things, he will objectively be happier than the aformentioned Sister of Charity.

You're confusing emotion and true happiness, the satisfaction of the deepest desires of the heart. At least I hope so.

Regardless, mobsters aren't happier by either measure.
