Joking aside—well, mostly—with the number of people we have on our fold, we could actually use our numbers to our advantage, and adding traps, snipers, roaming groups, and our main force into the mix would just be overkill. In addition, despite the group we took care of last time, who had evil intentions toward us, we were geared toward recruitment and poaching others to join us instead of outright committing murder.
To be fair, this approach was a little idealistic but realistically speaking, the reason randos popping out of nowhere to do bad stuff was just that they had to.
