I see it more as just a tool then an actual being.
It's just the concept of how it can judge whether what its hitting is good or evil which interests me. Like its boundaries, how it would know, does it react instead to the person using it instead of the person its striking, etc.
Personally, I think it looks at the person using it. A evil person would use it against good, while good people would use it against evil.
