There's an interesiting point in the Sonny-Tom-relationshop. While they discuss what to do after the hospital incident, Sonny bursts out: "No, no, no! Not this time, consigliere." Why does he call Tom "consigliere"? Is he trying to ridicule him or his new function or their new relationship as Don/Consigliere? Note that a few seconds before he calls him "Tomanoutch".
Tom says "Sonny" after almost every sentence.
So, what's this consigliere-reference in this scene? Why is Sonny saying it in a moment of great anger.
He's not angry at Tom; he's just made up his mind on a course of action. Of course, just a few minuts later, Sonny accepts Tom's caution to consider the disastrous results if Sonny pursues that course of action. Also, don't forget that in a previous scene in Vito's office just before they are brought the fish in Luca's vest that Sonny calls Tom Consigliere when he asks him for advice if Vito dies. When he calls Tom Consigliere in the scene you are referring to, Sonny's simply emphasizing that he intends a course of action that is a departure from Tom's proposed course of action and Tom's course of action is a function of his role as Consigliere. Remember, Tom's Consigliere role is to advance the interests of the Corleone family at the least cost to the Corleones and certainly without spilling blood.
