he didn't just straight up kill them all, he questioned them first and was satisfied with the information he got from them and that they were only there for the 'tree fruit' and pretty much just killed them all. However, this time it involves merchants and slave traders.. So, there's bound to be more information and he can figure out if anyone knows about his village, by simply probing that he "knows of a village" and see how they react. However, Idk how long the whole charades going to last.
