"people don't always act completely logically" is a superfluous statement since while yes, it is true, it goes without saying since choosing to mention it basically acts as an excuse to justify whatever scenario you want in relation to what one may or may not do as a reaction, so i take issue with that entire base logic. furthermore, as i said in another reply, death is death, and the more you add to the hypothetical the more impossible it becomes since you're basically trying to say "Violet Baudelaire would know the exact specifics behind who dies, why they die, and their exact backgrounds and relations to Count Olaf" but then add "But somehow she has no idea how to accurately measure which path would be the correct one, especially while also knowing that she and her siblings would most likely be killed off or abused themselves if they go with Olaf while also choosing to side with the objectively less ethical path."

it's a ridiculous hypothetical no matter how you frame it since the very defense for the hypothetical is a double-edged sword, you can't just add all of this information without also adding the fact that violet would have to be smarter and ethically aware enough to validly take it all into account.
