Well, that might be the case, but we should consider that, as of now, he's acting as Mashima's trump card of sort against Hades, in order to save Team Natsu...It would be strange of him not to help out in the battle, wouldn't it?

Besides, I do think that Laxus is several times stronger than the members of Team Natsu, and that his defeat at Natsu's hands was mostly due to him having lost control and entered that berserker-like state after failing to exterminate Magnolia's inhabitants with Fairy Law... Which, if you ask me, might come in useful against Hades: I don't think that Laxus would have so many problems pitting his Law against Hades' to see the outcome, unlike Makarov...
