Would Wily think “hey this is too much and too many people would get hurt or die.”
He never seemed like the global genocide type to me.
Also wouldn’t he be appalled that the Reploids infected with his Virus would see him as “less than” and want to see him and all humans destroyed?
Even if Wily took over the world and destroyed Megaman the future would have been much better off. Wily would likely never have killed Dr. Light since he had plenty of chances to before and didn’t. Wily clearly wants recognition of his “superiority “ by Dr. Light.
Wily would never have built Zero (maybe not even Bass and Treble). Without Zero and X there would be no Maverick or Elf Wars.
Wily would have passed in time and the world would have moved on. After all his rivalry with Dr. Light gave him “purpose in life.”
Wouldn’t the most logical thing be matter that fell in would be compressed into plank cores?
