What's the meaning of "only the fiercest even could"? (especially "even")
Below is the script from Wonder woman. Little Diana and the Queen are looking at the most powerful weapon they have.

Diana: "Who would wield it?"
H: "I pray it will never be called to arms. But only the fiercest among us *even could*.
And that is not you, Diana. you're safe. there's nothing you should concern yourself with."

I'm curious about the role and meaning of "even" here, cause I'm more familiar with the usage of even in negative sentences like "Even the powerful among us couldn't do that.", "She can't even do this."

So in this sentence, does it mean something like "the most powerful person among them could *barely* wield the weapon?" It is possible to wield it, but it was hard for even the strongest person?

Answer

“Even” has to do with the fact that the question asked “would” (implying that it might be a possibility for anyone or many) and the answer conveys that it would only (even) be possible for the fiercest.

Q. Who would run 100km per day? That’s nuts.
A. Who even could? (Even if people wanted to, most just wouldn’t be able)
