Well, that's what made him super evil- but as soon as he saw the monitor feeds of the nanite data and of the horrific experiments being performed by Mindbender, he instantly was in evil-love with them. "Oh look- people being horrifically experimented upon in inhumane ways by a crazy scientist...they're beeeautifullll..." is not the reaction of a good person. On anotehr note related to the nanites- was anyone else perplexed at Destros' reaction to his nanite mask? After it first goes on, his initial reaction is pride at fulfilling his family's legacy- then his next immediate sentence is a reaction of horror and revulsion in a "what have you doen to me?!" way. That was just confusing- it was like they wrote two different reactions for that moment to use as alternate takes of the same line, and then just decided to string them back to back, logic be damned.
