"Take her away from the battlefield. You are not suited to fight me." He-El withdrew his gaze from Thanos and said calmly to Pietro Maximoff, who was holding Wanda Maximoff.
The siblings had never been truly determined to fight He-El. More than anything, after learning of the future, they had been swept along by the Avengers, Nick Fury, and Stephen Strange into opposing He-El.
Ever since gaining their abilities, they had felt that they ought to do something, yet they had never found what that something should be. So they had gone with the flow and joined everyone in fighting the great villain, He-El.
Yet Pietro Maximoff and Wanda Maximoff had also experienced how He-El had once saved their lives and given them hope, leaving them with doubts.
Was He-El really so unforgivably evil?
Holding his sister, Pietro Maximoff worriedly brushed the hair from Wanda Maximoff's forehead. Looking at her gaunt, skeletal face, his heart ached. He raised his head to look at He-El and could not help asking, "Will you really destroy everything? Humanity, Earth, the universe... Will the curse inside you destroy it all?"
Stephen Strange, Nick Fury, and the Avengers had constantly reminded him that He-El had only appeared so benevolent toward Earth because of the Infinity Stones. Everything had been intended to win humanity's and their trust, so that he could obtain the Infinity Stones.
Only later had they learned that He-El sought the Infinity Stones in order to remove the curse within his body.
Would the curse in his body destroy the world?
In truth, the Avengers, Stephen Strange, Pietro Maximoff, and the others did not know. But after He-El killed Nick Fury, and after the Dark Lord Dormammu worked with him to kill Ancient One, everyone had concluded that He-El was no good person.
