Kinda related to the other ask; the way Thanos "handled" Loki in IW (manual strangulation) is extremely personal and sadistic. It's worth noting that, although it's most likely not the case here, that such sadism is also commonly sexually motivated. ...Do with that info what you must :P
I have heard of this kind of thing before, strangulation being the most intimate way to murder someone, and it really makes me wish we could have seen more of how Loki’s alliance (and relationship) with Thanos developed after he fell into the wormhole at the end of Thor. It was kind of the driving point behind his whole villainy in Avengers, but it was left mostly to shadows and oral exposition with very little explanation as to how and why--and to what length Loki was truly responsible for his actions on Earth, a topic of intense scrutiny and discussion (and sometimes discourse) all over this site. It’d be great if, during the course of Loki’s space/time jumping in the upcoming series, we get to see how these two massive personalities first met and finally receive answers to some of these burning questions we’ve been asking for years.
Because of all the people Thanos killed, he killed Loki the most personally. And this was definitely a personal method, just as you said. Even Gamora, his own “daughter”, he just flung into a gorge like a sack of garbage. But for Loki he reserved the slowest, closest, most brutal death of any hero that has appeared onscreen. That speaks volumes about how great of a danger he viewed Loki, in my opinion. Maybe he wanted to make sure Loki wouldn’t live to trick him again, the hands-on approach being the surest method of extermination. Not only choking but also snapping his neck--and making sure his brother was there to witness it all. That made it practically a double murder.
I’ve thought about this at length, just how furious Thanos must have been to be betrayed by Loki. I don’t think there’s anything Loki could have done to talk his way back into Thanos’s good graces. He was already dead from the moment Thanos saw him on the Statesman. And there were a number of ways he could have chosen to kill Loki, or have his Children kill him. But he took the slow route, face to face, and looked straight into Loki’s bleeding eyes until the moment the life went out of them.
But in relation to the ask you mentioned, which is less meta and more kink, I agree that it definitely lends legitimacy to the idea of a sexually-charged murder. And since so much of Thanos and Loki’s “business arrangement” is left largely to speculation, how they arrived at this violent, intimate moment makes for some pretty compelling (and deliciously whumpy) fanfiction. 😈
