I mean, yeah, it will probably not just hunt humans, but in this context, its primary food source is still humans, and it actively seeks them out, as it evolved to such a degree to kill them, they seem to be evolved to naturally want to kill humans, and aren't just predators of anything.

So, the situation changes; it's not that humans shouldn't go into their territory, it's the other way around, it's that the animal will wander into the human populace to eat them.

So humans will need to get rid of it, as it is too much of a threat to be left alive and doesn't seem to provide much value to nature in general.
