A few explanations about my suggestions (just so you know that I actually did think a little bit

):
I'm never good at spotting gifteds, even as a wolf, so often I chose somebody who I just thought could be dangerous in general, mostly because of an abundance of sanity. It turned out that those sane people were wraiths.
In Night 3 I had no idea about any gifteds. I chose
Brinn because she seemed both innocent and sane, and after that insane
Durelin lynch I thought getting rid of her would send the village into utter madness.
In Night 4 I suggested
A Little Green, out of a gut feeling. I just felt that she had a special role, whether it's gifted or Frodo or even a wraith. I was wrong.
In Night 5 I suggested
Rikae out of more or less the same reason, plus she looked too innocent to be kept alive.
In Night 6 I spent all day thinking about who to send only to forget sending anything in the end.
In Night 7 I suggested
Aganzir because she was after
Legate who I thought was a wraith. I did not suspect her of being the ranger, but I thought a dead
Aganzir would have been less harmful to
Legate than a living one, because he seemed to look innocent to most other people.
In Night 8 I still was more confused than ever and chose
Nerwen because out of everybody, I thought she was most likely to "get it right".
