So, during the fight with Sho and Agito as Gigantics. Do you think Agito would have killed Sho with the gigasmasher? 

 

I think so because Agito attacked Sho with really negative intentions since Sho wouldn't join him. For whatever reasons other than that. I don't know why Agito even considered it as Sho was not a threat.

If it were to suit his needs, more than likely. There is an underlying care for Sho within Agito, but it never has or will stop him from reaching his end goals. But Sho has a massive strength all his own so it would be difficult for Agito to defeat him.
