Why would they become outlaws?

For one thing there's no Magic Council who could put the blame on them and for another they were the ones who were attacked and defeated Tartaros in their counter-attack. Not even the Magic Council would argue against Fairy Tail in this situation. And on top of that they have the testimonies of the Sabertooth members and !!Doranbolt!! to proof their innocence.
