Another thing is Victor's daughter is highly unlikely to continue to survive in such an environment regardless. In reality anyone facing such things WOULD either become desensitized, go crazy or wind up dead.
Whether Victor is telling the truth about his daughter or not, my main point is that it doesn’t justify how he treated the MC and his group. As for his daughter’s chances of survival, even if she’s ill, it’s difficult to say. Everything in this world is still very new. The MC lost his friends just a few months before the story begins. They had all arrived together on vacation to explore South America when the zombie outbreak occurred.
We know that fortified cities controlled by military factions exist, and it’s likely there are various communities scattered around as well. Children were seen in the city of San Fernando, which means vulnerable people like kids, the elderly, or those with disabilities must be managing to survive, even if only in small numbers, in an apocalypse like this.
Naturally, the chances of survival for these individuals decrease during zombie attacks or clashes with other humans, especially when illness is involved, whether serious or minor. The situation becomes even more dire when medicine is in short supply, which appears to be the most precious resource in this world now.
As for Victor’s daughter surviving or not, that’s not really the issue. What truly matters is that Victor could have negotiated for the medicine he needed and left safely, maintaining good relations with those who helped him. Instead, he chose greed, taking all the medicine, trying to profit, and prioritizing his daughter’s survival at the cost of others. If he had only taken a small or reasonable amount and fled, it might have been forgivable. But betraying people who offered their help in such a selfish way is not only unjustifiable; it’s practically signing his own death warrant.
So, of course, I didn’t spare him in my run. But like I said before, I strongly suspect that whether spared or not, he will come back to face us again. It is almost certain. I assume the story intends for him to be an antagonist whose feud with the MC lasts through at least part of the plot. It is only natural to have clearly defined enemies tied to the protagonist who carry real significance and weight.
