I think you're waving away my point. I was trying to say that people 1000 years ago disliked bears and wolves because people would die. Roads weren't safe. The problems with boars pale in significance to the problems bears and wolves caused. OP said "we're currently having large issue in Europe for having eradicated most boars' natural predators" - but these issues aren't larger than the problems that boars' natural predators caused, which would've been obvious to anyone who lived at a time when they still existed.
