But he wouldn't use it, it's entritly out of character for him to do so. There are other spells that can kill like conjuring fire or blasting your oppoent hard enough to casue bodily harm, those are types of speels he'd use. But sense those are the types of spell he'd use in fight, not the killing curse, ones with another purpose but have a potiential lethal factor, That is why I don't think he's win.
