The Nuances in Distinguishing Attackers from Bad-Guys

A few days ago, Madeleine held up one of her many mermaids, from a set where each one was distinguished by a unique hair-color and matching tale, and announced, "This Ariel is a bad-guy."

Eventually, Daniel got around to following up on that classification and the following dialog ensued:

Daniel: Why is she a bad-guy?

Madeleine: Because she's attacking this Ariel [another in the set].

Daniel: Even though some people attack other people doesn't mean that they're a bad-guy, Madeleine

Of course, this seemingly amoral outlook scared me, at first, so I asked for a bit more elaboration, which Daniel provided, for cases where attacking parties might not necessarily be bad-guys:

"Just if they're attacking because of a war with army-guys. They're just attacking because of one country."
