User blog comment:WaffleMinifigure/Waffle's Guide to Mary Sues and How To Prevent Them/@comment-12609788-20130718165319

I think it is more important to make sure your characters are good characters instead of mary sues.

Killing your sue won't necessary make them not sues. Atleast not when you would have stopped writing about that character anyway.

By the way, The Universal Mary Sue Litmus Test is somewhat flawed too.
