Makarov will strike back anytime regardless of who the enemy is if his "children" are hurt, you should know that by now. And in the Galuna arc they didn't even want to take revenge for Gray, it's Gray wanting to settle his score with Lyon, Natsu and the others wanting to prevent Deliora's revival. Well Erza initially wanted to forcefully take them back too, so no revenge for Nakama thing. In the Fighting Festival, they were basically fighting against each other. As for the Oración Seis, they were needing Wendy to heal Erza more than revenge.
