I believe Dr. Eggman would be forgiving. Metal Sonic recognized her as a fellow badnik and Eggman seems more interested in her as a machine than an enemy especially given this was around when Dr. Starline invaded so it was somewhat of a truce at the time.
Yeah, Metal is his best creation afterall. Every times Metal failed, he just moved on and made some adjustment / upgrade on Metal.
He doesn't even treat Hardboiles the same way he treats Metal.
The question is will he adjust / change Metal or not after he knew.
