But, if a creature is breed for evil, and knows nothing else, does it make the creature evil? It's the 'which is worse, the gun, or the shooter' concept.

The shooter is evil, yes, but still, you would have to disable the gun in the first place. If a tool is used for evil against good, destroy it. If not, then try to redeem it.
