Another possible psychopath: Joe Massino.
You really need the disability to feel no shame or guilt to rat on everyone you know.. And didn't he order the murder of Gerlando Sciascia because Massino thought he was questioning his authority?
Well according to Massino, Sciascia was murdered for murdering somebody himself. He is said to have questioned Massino's leadership abilities and supposedly bitched about TG's cocaine problem as well. I'm guessing all of it played a factor in his murder.
But I have to agree with you about the rat thing. There has to be something really fucked up with your mind if you're willing to rat on the people you grew up with.
