New Fan Theory Argues Why Thanos Didn't Kill Captain America in 'Avengers: Infinity War'

Thanos is arguably the most powerful and vicious villain in the Marvel Cinematic Universe, as he not only killed multiple individuals with pure strength, but also wiped out half of the universe with his snap, now know as "The Decimation."

However, on his journey to balance the scales, he's spared a fair share of lives, including Thor, Iron Man and Captain America. And a new fan theory posted to Reddit attempts to explain The Mad Titan's rationale behind not ending Steve Rogers' life in Avengers: Infinity War.

The theory, posted by Office_Zombie, begins by explaining that Thanos doesn't consider himself a bad guy, and he believes he's doing what's best for the universe. Not only that, but he considers everyone else simply misguided.

"And because he is the good guy in his mind, he doesn't kill for any sort of pleasure, mostly out of a misguided sense of duty," the theory states. And due to the fact Thanos doesn't see others as "bad people," he sees admirable traits in some of them, such as Tony, who he said he respected. That brings us to Captain America.

When Thanos made his way to Wakanda, he encountered Steve, who was able to catch and hold onto his Infinity Stone-donned hand. Did Cap really posses the strength to hold Thanos back? Well, not according to this theory.

"Thanos was trying not to hurt him," the Redditor argues. "He only looked at Captain for a minute like that because he found something interesting in [him]; and maybe he was a bit surprise by how strong or determined Steve was."

Instead, Thanos punches out Cap with his right hand, which is obviously less powerful than the Infinity hand.

"He... didn't want to hurt Steve more than necessary, and he didn't want Steve to hurt himself trying to fight him (Because we all know Steve would have fought until he was dead)," the theory continues. "If Steve died in the snap, so be it. But he wasn't going to chose to end Steve's life because that wasn't his purview."

We think the theory is pretty valid, because as heinous as Thanos' actions were, it was evident throughout the film that he wasn't doing any of it for himself, but instead he even seemed somber at the end due to all the casualties he caused.
