Let say someone creates a tool, an android which is designed to kill everyone that believes in a religion the creator does not like. Is that tool neutral?

Only way to repurpose that tool is to destroy part if the tool and replace parts. It is now a different tool.

I say intention of the tool design dictates if the tool is "neutral". That hammer analogy is tool simplistic to the tools we can now create and are attempting to create.
