Well, that certainly takes the piss out of my answer.
In that case, I'd make Bill O'Reilly a bleeding heart liberal. But only after he becomes a well-known conservative pundit.
iirc, 5-12 are mass produced models, and use dummy plugs based on Kaworu. No idea if they actually have souls, since syncing up with a pilot isn't much of a concern.
If they do have souls, it's inconsequential to the plot.
I don't think it's ever brought up explicitly. It's been a while since I've watched eva though.
Also, this is my favorite derail ever. From "Hey, what gender are you?" to "Whose soul is in this robot?"
