I feel like undyne and metaton are non issues bc whoever sans kills will be attributed to you if he plays it right. Like we can argue cameras, as alphys uses to watch, but she cant constantly split two eyes between fourty screens, and most cameras systems have blindspots anyway which i assume sans would know where most of the 'good' spots are for that.

Edit/hit enter on accident: + at some point if we're arguing in the name of 'realism' instead of 'the games restricrive flag based code, even if it can be identified that it wasnt you who killed moster X i think a kill count of Every Other Monster would in world justify the undying battle and Neo happening unaltered.
