Seems as if Phil Leonetti really disliked Skinny , but he felt opposite about Chuckie and Yogi. Even talking Nick Sr. out of killing both brothers , demoting them both instead due to Phil's reasoning with him. I do not know about snatching purses from old ladies ? If memory serves me didn"t Skinny beat his partners out of their share of the armored car heist ? Also the stories about never paying the bookies when he lost , makes you think that Leonetti seen something bad in Skinny as a kid. As far as that point goes it takes one to know one.
