Tom, and to some extent the rest of those on the dev team, do not believe that it is our job to shield children from the realities of the world.
I would not, in any way, support graphic roleplays of rape or other gruesome scenes being posted publicly. None of us here condone rape, or believe that it is good to glorify it in any way.
However, as unfortunate and unpleasant as it is, in the milieu in which BattleMaster is set, rape of peasants in war was commonplace, and I don't believe it's appropriate to trivialize it by simply ignoring its existence, either.
There is very little that the particular option is better at than other looting methods. If someone orders it, then they should have a very good reason why they choose it rather than the other methods. If they don't, then raise holy hell about it.
I think that provoking heated, completely in-character discussions about the validity of such actions is totally acceptable, and something that I would hope to see options like this do within the game.
