And even if there isnt a spell that can kill anything, its possibly there is a creature that can kill anything, like Death or God, and I was also thinking a genie, like I wish a Levithan was killed and its like done, but it SPN, a ginn fufills personal wishes while it kills you but doesnt actually perform the wish, so I dont know of any other creature as of now, maybe Death might hand Dean his scythe to use on them, the one weapon that can kill anything and when I say anything, I mean, anything, not the Colt that can kill anything except for 5 beings
