What is worse, blowing someone up on a battlefield or capturing them and sacrificing them later? I’d say the latter because the death is relatively quick and painless and included a soporific to calm the victim down. The latter was what the Aztecs did. Their wars were for capturing prisoners, not killing enemies. I don’t know… that sounds like their sacrifices are more moral than blowing someone’s legs off and letting them bleed out. I’d call the latter a lot more moral than the former. Because less suffering is good, right?
