So I have seen a few times that someone (mafioso, vigi, SK, etc) attack their GA despite KNOWING that they are they GA
And when that happens people start arguing if that is GT or not
Personally I think its gamethrowing (unless the GA was trying to kill you) because they are an extra vote for your faction, they can still protect while dead but having them alive is a lot better than having them dead since you dont have that extra vote for you
