While Scourge is a known villain with a ruthless personality, his focus is primarily on Sonic and his friends, often trying to take over the world or defeat Sonic. Amy is not typically a central target of his attacks.
In fact, in some instances, Amy has even helped fight against Scourge. For example, in the Archie Comics, Amy is a member of the Freedom Fighters who oppose Scourge and his forces.
It's important to note that fan fiction and other non-canon works may depict different storylines where Scourge might kidnap Amy, but this is not a part of the official Sonic canon.
