Billy Budd.
That white-haired main character boy from Karneval.
Pretty much all characters who are supposed to be the paragon of purity, goodness, and so forth and that the creator of the series has essentially labeled in giant day-glo letters YOU ARE SUPPOSED TO LOVE THIS CHARACTER YOU ARE SUPPOSED TO WANT TO PROTECT THIS CHARACTER BECAUSE YOU DAMN WELL KNOW THIS PLOT IS 80%+ ABOUT CHEESILY RESCUING THIS CHARACTER. It's a huge turn-off for me, and often I simply stop watching shows/anime if it seems like the premise is going to turn to damsel-rescuing.
