You mean that Kirby might have been DELIBERATELY intending some comparison between the Marquis DeSade and DeSaad? What a thought! ;)
I wonder how many perfectly innocent and delightful Marquis De Sade are now permanently tarnished with comparisons to their distinctly pervy ancestor/descendant?
It must be like being give the previously perfectly decent and ordinary name Adolf in 1920's Austria, by the time you're old enough to realise you now share a name with the human embodiment in insane evil, it's sort of too late to change it.
