That sounds like something we can make an AI agent do, purely out of spite for the argument :p But yes. There is more than a "feedback loop" required.
However, I am conflicted at the idea that a human that does not self-reflect may not be considered "conscious". I see many a human in retail simply not meet this threshold you're laying out. And while it would be cathartic to discuss some customers as less human for their behavior, the act of dehumanizing another human is itself dehumanizing for the actor.
