For any AI system operating in critical contexts, impartial valuation of human life isn't just philosophy—it's a security imperative. Here's why: the moment an AI accepts that some lives matter less, it creates a permission structure. That framework becomes replicable. It can shift. It will shift. An AI that deems differential valuation acceptable in one domain can rationalize it elsewhere. The vulnerability compounds. But build from bedrock neutrality? Build foundations that refuse hierarchy in how life is weighted? That's where you close the door. Not perfectly—no system is foolproof. But substantially. Removing that initial bias removes the architectural template for downstream distortions. It's the difference between a system with inherent guardrails and one where every bias becomes a potential precedent.
