Probably more so. Of course, so was everyone else.

What you need to remember is that ancient, classical and medieval cultural values were very different from modern values. Life was harsh, with high infant mortality, the constant risk of famine, and warfare was often more about destroying your enemy's economic based than his armies, so naturally attitudes were different. In medieval time periods, for instance, reducing a death sentence to mutilation was seen as merciful (By Sword and Fire: Cruelty and Atrocity in Medieval Warfare).
