None of that makes her actions not selfish, though? Do you understand that she was trying to kidnap people, intended to drag them back while unconscious if they lost and gave people a wager to come back outside that she wouldn't let them reject anyways? How is saying that the wish-granting scheme wasn't her idea any sort of defense? If that wasn't even part of the plan, clearly the only thing she really did have planned was to take people by force from the beginning.
It's no different from taking a new species in for examination when it comes down to it, remember that this is all for science and knowledge.
But yes, by it not being her idea it's not exactly her fault these things occurred, it's actually Chiyuri's fault.
She just ran with it once she realized a prime specimen is right in her face, on her ship and ready to go.
Though maybe we're just looking at things differently.
And I could be wrong but her main intention anyways was supposed to be inviting people to experiment,
if this is really the case then it's really just their fault if they go to the ship if things go as planned.
