No, not really. I don't mind characters dying. I don't even miss my faves, I mean I can always go back and re-read or re-watch parts involving them.
And you've just reminded me of an uproar Jman's death caused back in the day on some older forums. There was that guy who just posted "I HOPE JIRAIYA DOESN'T DIE" like a hundred times in one reply, lol.
