Fairy Law is indeed Magic nuclear deterrent spell that should not be used so easily and lightly.

Speaking of which, Laxus mastered Fairy Law right? If he actually pulled it off (what if it works) in his attempt to kill everyone in Magnolia, civilians and guildmates alike, will that affect his lifespan and kill him?
