In Sammy's self serving book he takes shots at just about everyone but I dont remember him saying anything bad about nino. I think he called Roy demeo a psycho path or something
Yeah Sammy told a story about him and Roy sitting in a diner with a bunch of senior citizens and Roy said he could clip all of them in a matter of seconds or something like that. No idea if it’s true but I honestly wouldn’t doubt it. When you kill the amount people Roy did and dismember them like it’s nothing it’s clear you are capable of any kind of evil
