[@fer1323] Though if we're going philosophical here, killing for fun is about as evil as it gets. If they were just animals you could make the excuse that they don't know what they're doing but...well some of them are quite intelligent. Then you have Froslass that, as the pokedex says: "When it finds humans or Pokémon it likes, it freezes them and takes them to its chilly den, where they become decorations." I mean that's pretty bad, especially since it's an intelligent creature (it used to be human)

Really by that kind of logic, evil would only exist if one was committing these acts in the name of evil...which really doesn't happen (aside from cartoons).
