Mad Scientist-type characters... I feel like it's really hard to judge them as "good" or "evil" when there's even a little ambiguity, until the author has revealed all their reveals, and the story is over, and we as the audience have all the facts available to make our judgement calls.
Sekirei is one of those series, Minaka is one of those guys, that I find really hard to judge--yet.
I mean--well, if Sekirei exist, and were dispached to Earth because Earthlings have "exhibited the potential to become Ashikabi"--
That was a humongous atomic bomb of a line that Miya dropped, because--
If the part of Minato was played by daniel_gudman said:
"Humans exhibited the potential to become Ashikabi"--wait, this means you've gotten Ashikabi elsewhere before? Then that means there's at least a third alien species, that could be Ashikabis for the second, you Sekirei?
Maybe Minaka's worried about that
other race of Ashikabi showing up in more spaceships and being like, "Nice planet; we'll be taking it, now". That's something I'd be super-duper-worried about.
I guess my point is, Ms. Mangaka has really invoked Fermi's Paradox without actually addressing it, here.
(Anyway remember that Minaka was sad about humans being affected because that was
unexpected, not because it was
bad.)
So I guess what I'm saing is,
Until we know whether Minaka's preparing for like a Borg invasion or whatever, I have a hard time condemning him.
