This is what Nebula said. In the final battle, Thanos personally admitted that he sacrificed his adopted daughter Gamora before getting the Soul Stone.

Then the stupid Star-Lord became stupid on the spot and hit Thanos hard enough to wake him up...

"Ahem, why are you looking at me? Why are your eyes so unscrupulous?" Roger looked at John's strange eyes and couldn't help but complain.

"Nothing, I just thought that you often use your soul as a pawn..." John took out a cigarette and smiled faintly.

As soon as these words came out, everyone at the scene looked at Roger. If the other party had this ability, then wouldn't he be the one to take the soul gem?

"If you can help get the soul gem, please help us..." Future America stepped forward and said.

"Look at what I'm doing, keep going~ Roger pointed at John and said, "This guy is a little more powerful than me. He has borrowed money all over hell, and he has never paid back..."

"Please, help us..." The widowed sister also came forward and prayed.

Roger looked at it. She was much prettier than the movie version. It seems a bit pitiful that such a beautiful girl lost her soul in that valley...

"Ahem, just leave it to me and Roger. I believe we two mages can get the soul gem from there." John coughed.

Roger glared at John, why the hell do you want to hunt game now that you have Zed?

John pretended not to see it, took out his cigarettes and began to cover up.

"Then I'll trouble you two. Nebula will be responsible for taking you two to find the Soul Stone, while Steve and Thor will go get the Reality Stone. In this way, we will have all the gems collected."
