I'd have trouble with even an alt dying before they reached the end of the story I want for them, I couldn't bear to have my main character killed off prematurely. The only thing that would make me consider it is if the end was fitting, and left me with no regrets. If I could look back at that character and say, "They didn't achieve what I set out for them to achieve, but they had a good run."
But even then, it'd probably still bother me.
