Yeah so true, I always imagine that dynamic if you think about something like a father with wife and child in a perfectly safe spot, then saw 3 girls are being chased by zombies calling for help, if the father will help them he will compromise their safe hiding spot endangering both his wife and child, if he doesn't save them his moral principle is being question, of course I'd choose not intervening, what am I that dumb?

I feel like everyone in the comments is overly hard on the MC for how he is currently interacting with the all girl adventurer party But I'd say the way the girls are being treated is realistic for the time especially if non of them have specialized skills that they're good at.Also if MC jumped in at that moment during fight he doesn't really know the kind of backlash it would have, and he doesn't just have to watch out for him but his daughter and wife. What if when he's out someone affiliated to them goes after them because he involved himself?
Maybe if they add the female team to there's it might alleviate the girls problems.Or he gives them a discounted price to buy any meat off him and his family party, do they could still remain independent but have help.
