The barbarian are rarely gentle. Raiders don't generally believe that city-bred are capable of honor; some tribes don't even consider their victims to be human beings. Combined with warriors hungry for glory and a tribe desperate from starvation, a barbarian raid can be gruesome and overwhelming, replete with rape, torture and wholesale destruction. Storytellers should consider their group's tastes before portraying these elements. They shouldn't be included if it would ruin the enjoyment of the game and lose their impact when presented as shallow shock. You may wish to describe the impact of a raid in general terms or simply concentrate on the aftermath, portraying the brutalized survivors and their razed homes.
The Lunar Exalted have an incredible amount of influence when it comes to directing a raid, but they are products of practical, brutal septs that raised them. On the other hand, Exalts are, by definition, exceptional people; basking in Luna's light makes them a breed apart, above tribal law and forever severed from the old assumptions that once guided their thoughts. Lunar Exalted can make their own moral choices, but they may have to face the resistance of their people. Turning a savage warband or nation into moral warriors can serve as an excellent focus for a story or series.
