@Prime: Not always - remember Gajeel? He was cruel, brutal, full of aggression to Lucy and Levy. Erza, Natsu any others are really bitches for their opponents, burn them, cut them, beat them to bits. But it was war between guilds, not internal persecution.

I pretty sure it's not about the any characters itself, rather I think he want to show some behavior, which should be practiced - if it is war, fighting with your enemy is right, but in guild, mobbing like that isn't allowed, is something bad.
