I think that's pretty obvious really. If Marik wants to destroy everything, obviously that includes himself. *nods* I just thought that it would be fun to write in a semi-insane manner to see if it suited him.

LO! Damn you, now I've got this mental image of Bakura curled up in bed with Marik trying to read him a fairytale, and constantly getting interrupted by demands for illustrations, at which point Marik drags arndom passer-bys in with the Rod and kills them so that the story can have multimedia. XD
