i don't think eva stratt chose to be in the position she's in. no one with half a mind would choose to take on that kind of insane responsibility knowing very well that you will be blamed for everything, doesn't matter whether you control it or not.
there was a vote, which means there was a list, which means they probably came up with criteria over several weeks of arguments and discussions. then, they tried to find people that fit as many of them as possible, and that's how you get said list.
a very, very short list. diplomats, politicians, leaders — capable people that are good at what they do and speak several languages and seem like they could handle the pressure. people that are already perceived as something other than human.
then, they voted. maybe in rounds, maybe the list was short enough to sort it out with one. either way, eva won, but it didn't feel like a win.
it felt like being chosen as a sacrifice, a scapegoat, turned into someone who gives up being human for the greater good. they honour you, at first, revere you maybe, but people care about exactly two things: money and power.
so soon enough, saving humanity became secondary to selfish gain. eva stopped being the noble leader and became the enemy, and she knew it was going to happen, knew it was only going to get worse. but she didn't really have much of a choice, did she?
she has no immediate family.
she doesn't even have a dog.
she has no one who cares about her as a person, a human.
what's one life compared to billions?
