I do not wish that the writers use bad words just because they can.
But I think that killing many people is worse than using some words.
And the example of melianos shows, that a nice and polite way of talking can be unfitting to some situations.
PoE uses the f word several times (eternal rantings of Durance) without being a porno.
Writing must be consistent with the situation and in a bad situation (such as killing people) a bad language can be appropriate.
