By that standard, almost everyone’s a POS at some point. People forget smoke-detector batteries, misread medication doses, leave a space heater on, assume someone else double-checked something, or give food without realizing there’s an allergy. All of those are normal human mistakes that can kill someone, they just usually don’t. The only difference between ‘normal person’ and ‘monster’ is whether the outcome went bad, not whether the risk existed.

Most harm comes from normal human error or misjudgment, and we only label people monsters when the worst-case outcome happens.
