way back, when weir and de filippis were writing 'new mutants', they also had a suicide storyline cancelled on relatively short notice. and that was during marvels 'experiemntal' phase, when they were publishing crazy stuff like x-statix. is it possible that marvel have never released a suicide-story? i cant recall they ever have. then again, my knowledge is rather limited.
