Exactly - Turin made a lot of his own problems. And while he got a pretty tragic fate, I don't think he deserves the 'kill Morgoth' hit more than others who also suffered and did little/nothing to bring it on themselves!

#4 is the most real answer I could come up with. I mean, it's all well and good to claim you'd be Galadriel or Finrod or someone else heroic, but I just can't see myself leaving Aman in the first place, even before Alqualondë.
