SSSSSSSSSSH. We want to CRUSH the cataclysm 'theory', not give it any more breathing room! XD If Inafune says Zero didn't do it, he didn't do it. XDDDD He could have been crazy when he woke up for any number of reasons, form circuit-rot to bad power to something not initializing right to being not fully programmed completely... (actually, I've been thinking about this further, plan to do another post shortly.)
And, face it, the Maverick Virus is now like the Minovsky Particles in Gundam- it's a convenient generic catchall for everything that needs a quick and 'woo scary!' explanation. :D
