Pedantic
Legend
The Endless don't really have rules in that sense, except maybe Destiny. They mostly keep each other in check and/or mostly do things out of a sense of decorum. Death would almost certainly turn down the suit if Thanos somehow got in touch with her. I imagine the scene would play out a lot more with him going to snap, a pale hand coming up to grab his arm, and the other rearing back to punch him in the face before she yelled at him.I mean, she would certainly hate it. But does she dish out vengeance? Or would using the gauntlet be a violation of her portfolio?
Would Spectre beat be the first to arrive for vengeance? (Assuming his boss wanted it done?)
Vengeance isn't really her vibe. I imagine the situation would play out a lot more like a firm rejection, with a threat of more drastic action if he failed to get the message....and, given the nature of the situation, probably a visit to Desire, to ask what the naughty word they were up to.
