Bears do this in many parts of North America and in general northern latitudes, and people live in harmony.
You're appealing to fear, and the slippery slope here is eradication of all apex predators. That has done absolutely nothing for environmental conservation in the cases where it has happened.
Apex predators can be reintroduced to habitats without direct impacts to humans. Of course there are indirect impacts, like livestock culling, but those pale in comparison to the moral ill of endangering entire species. Imagine if humans were hunted by a more sophisticated apex predators. We'd want to keep our place in the ecosystem.
