I don't want writers to ever go there, not even jokingly or by equivocation. Not only does it pull me out of the story, but it makes sense to me that no one would ever hurt any meta like that -- given that there are hundreds of them, there are dozens with phenomenal cosmic powers, and they're almost all in one big, close-knit extended-family-kind-of-thing. When the Rogues killed Bart comes to mind. You don't tug on the cape.
It would be great if a little bird started rumors about several criminals who engaged in unnecessary roughness and disappeared shortly thereafter never to be heard from again. I mean, the superstitious cowards already should be nervously looking over their shoulders and whispering to each other about "that Max Lord guy".
