I was having a discussion with a friend who proposed the question of "who has killed the most people, directly or indirectly?".
She argued that it would be Karl Benz (inventor of the motor vehicle) due to all proceeding designs stemming off of his and the frequency of motor vehicle caused death.
I instead suggested it would be whoever had invented the first practical firearm. She then stated that wouldn't count because you could then go further back and state it would be whoever invented the first weapon in general, to which I claimed by that logic her answer would be invalid since you could state the inventor of the wheel. This was reduced down by her to "the first humans whom we are descended from" since we cant die without being born first.
Clearly this is ridiculous but it made me think if it was covered by an existing fallacy, feels very slippery slope like but I'm not wholly sure.
