From what we've seen so far, consuming a soul seems to satiate a hunter. After eating the cousin, the hunter didn't continue the hunt. Rather, it seems to take some time to, let's say, "digest" the soul and "become more human." So, I don't think a hunter would just continue chasing through a crowd of people getting smarter and smarter along the way.
Jeongtae seems to have survived under the idea that you don't have to outrun the monster, you just have to outrun everyone else.
