I honestly feel that Leonetti played a larger role in Testa's death.He thought he "Leonetti" was the future of the family.He watched as Testa avenged his fathers death and killed the guys who were involved including the previously mentioned powerhouse Narducci.He watched as Salvie built an incredibly loyal,young,ruthless crew.He watched as Salvie and this same crew not only were the front lines of the Riccobene war.But his crew alone won the war.Then Leonetti watched as Salvie Testa was written about in wall street Journal and described as the "future" of Philly mob.Leonetti's jealousy peaked and then he watched finally as Testa was engaged to Merlino's daughter and saw this as a final power play.Now,I am not saying that Scarfo was not weary and watchful over Testa.But in my heart I truly feel Leonetti,so ruthless,was the one who pushed his uncle out of fear and jealousy.Nicky "Crow" and Tommy Del sort of touch on this.
