@Narf really? They are innocent, they are but mere merchants that are hired by the "royalty", just like they said, they are hired to transport these animals. I'm sorry if this sounds rude but, it's literally right there. Page 22 panel 3, just from their reaction isn't it obvious? you don't need 200iq to understand the situation.
also from what you said, it translates to "we should mass genocide the Chinese because they are the first infected from COVID-19, they are all mass murderer, we also should kill those who travel internationally because they are helping the spread of COVID-19" do you realize what this means? it means killing 1.4 billion and with additional those who travel.
back to the manga. killing them won't give any benefit, in fact keeping them alive will provide more information regarding the spread of disease. and the fact they are cooperative to the MC is more than enough reason to keep them alive. if they didn't tell the MC about their destination, depends on the geographical feature, it will take more time to find them.
Being emotional is not how people should react, reacting based on emotion will only bring harm. when you are trained as a healthcare worker, one thing they prioritize to teach is to save everyone in an emergency situation, no matter what they did, what their nationality, their race, their religion, and else. this is called "Obligation to provide service" which roughly translates from my language. What MC did is the best course of action, he's nowhere near qualified to judge other people, but what he can is to help them and let the others who are more qualified do their part. the author able to depict a healthcare worker's morale quite accurately, and that's a plus point.
Please, don't @ me if you don't have a concrete argument.
if you take this personally and feel annoyed by me and my argument, feel free to block me, that way we would never pass each other on this website again, since, from the looks of it, your moral values are way too different than mine, and it will prevent another pointless argument.
