The whole Anastasia thing is crazy. But reports that came out after his death, paint the picture that he wasn't as disliked as we're led to commonly believe, atleast not by the entirety of his family, which is commmonly reported. He gets whacked by Gambino loyalists, guys within his own family. He has a large, "blue collar" faction that remains loyal to him consisting of Rava, Dellacroce & Jimmy Squillante. Squillante goes to the Commission and badmouths Anastasia after his death, it's presumed he's leaning toward the Gambino side, Rava decides to have him killed. Rava is killed as a result, either in Florida, by a hail of bullets in which he remains standing and tells Toddo Aurello "You ain't man enough to kill me", then they proceed to beat him to death, or elsewhere. The other account isn't as detailed and claims Rava was tortured and killed in front of his family. Those two counts aside, after Rava is killed, an attempt is made on Dellacroce by Gambino, in which a shooter busts into the Ravenite and starts shooting, Dellacroce escapes by running out of the backdoor. After this, sitdowns are had and compromises are made, Dellacroce is allowed to live, and is named "Underboss" in title. In reality he was given a certain degree of autonomy, and basically was a boss in his own right, of his own faction (The Blue Collared).
