Isso aconteceu com Loki?

Na época,

Thanos had two of the infinity stones, space and power. Neither of them give any particular ability to see through illusions. Loki's "trick" was to swear fealty they stab someone in the front; that is not a trick worthy of a god of mischief. Unless Loki was suicidal he had plenty of time to try something to avoid death; on the other hand, Loki's tricks are almost always illusions, and this one looked like his physical body.

No entanto, podemos trapacear:

Tom Hiddleston had a 6 film contract with Marvel. -- Thor, The Avengers, Thor: The Dark World, Thor: Ragnarok and Avengers: Infinity War makes 5. He is a popular character and they have the rights to the actor for 1 more film.

Não houve truques desta vez. Loki tentou enganar Thanos, mas Thanos superou e matou-o. Ele está morto de verdade desta vez, a menos que roteiristas ou produtores encontrem uma maneira de ressuscitá-lo. Isso poderia ser feito usando o Time Stone, assim como Thanos fez para trazer de volta o Vision. Isso pode acontecer no próximo filme, mas até então é pura especulação.

Thor: He's been dead before, but this time it might actually be true.

Aprendemos ao longo do filme que ir contra Thanos não é algo que se possa sobreviver ...

Even Gamora, who Thanos loved, didn't survive and gets killed during Thanos' hunt for the Infinity Stones.
