Eddis, Attolia, Sounis

Does anybody else find it troubling, though, that all the characters in these books seem to take both the efficacy and the morality of torture for granted? They take the morality of slavery pretty much for granted, too. These are historically accurate attitudes (to the extent that the culture approximates late-medieval/early modern Mediterranean culture), but I'm wondering how uncritically we ought to buy in to those attitudes.
