Kurins and O'Brian, in "Boss of Bosses," say that Paul's failure to attend Neil's wake and funeral counted heavily against him among the working stiffs in the family, and may have helped Gotti get away with regicide. But, in the Mob, you can never go wrong by following the money. Paul was greedy about sharing the wealth with the working stiffs.
I think most mobsters knew why he didn't go to the funeral. But it just gave Gotti yet another reason to kill Paul and made it easier for him to get support.
