Even if there is nothing in the rules (?), I'd recommend it. Maybe with the exception of willing sacrifices: "Here I come, mighty Zath, may I be worth of your purity!" For example Aztecs saw some sacrifices as a honour for the chosen one and his family. Such "political correct" sacrifices aren't evil in the cultural context (no, this is not a statement about the universality of human rights in our time :wink: )
