So even if there were Matoran of Shadow/Kra-Matoran not made by draining other Matoran of their light, they'd naturally dark and corrupt? I thought that the Shadow Matoran were only so nasty because the Shadow Leeches had drained all their moral light (and Gavla wasn't exactly pleasant even before then, with Vultraz being worse, to the point that his personality barely changed when he had his light drained), with the Element only gaining negative connections after the Makuta went bad (and expunged their inner light, making themselves unbalanced). Why would the Great Beings create any Shadow-aligned beings at all if the element was inherently associated with evil (not even going into Krika, a certain dragon, the Makuta that Teridax killed for not jumping on board with the plan, Shadow Stealer in his heroic days, etc.) and even if it is associated with anger and aggression, you can be angry and aggressive without being irredeemably evil (assuming that, unlike Shadow Leech victims, that's not all you have). Edit: Also, I just read that post about Matoran creation, what was preventing the Makuta from just creating new Shadow Matoran from scratch, is there some aspect to the machines/process that make Matoran that prevented the Makuta from just making Matoran of Shadow that way, or is the Element of the Matoran limited to preset options or what?
