No idea if he killed or not, probably not but my estimation he's probably a real gangster.
Given who his father was, I think it is very likely he killed at least one person. Remember how Scarfo sr. raised his nephew and adopted son Phil Leonetti? What makes you think Scrafo sr. wouldn't raise his son the same way? This was at a time when killing someone was mandatory to get made in the Philly family.
