@-Mushroom - they would all have died anyway... The world in this manhwa is apocalyptic and honestly, humanity or what is "right" is different from what is our world. Ofc, doc could have chose to die together with his fam but he wanted to survive so he chose to continue living. Can we blame Doc or any of them for staying in the town? Nah. Can we blame Guwon? I'm still not sure.
