Why was Johnny Sac planning on killing Tony in the final episode of season 5. Johnny asks him to come in the city at night and they'll talk, Tony then declares he was an iq of 158 and Johnny acknowledges? After all they've been through Johnny was really going to kill Tony only because Phil Leotardo didn't get the opportunity to torture Tony Blundetto? Is that proper justification for killing Tony? I don't think so, it doesn't even really seem like Johnny to do that, just suprising I guess.
