There was a time in old days when predators & humans were familiar with each other, At that time they understand each other behavior. They don't feel insecure each other company. Today world has been changed. World is more developed at the cost of demolishing forest, killing naturalul resources, covering land for plaza, metro city, away from natural life. These things made a huge gap b/w humans and predators. so that's why we rarely face predators in our surroundings as a result human fear has been increased and same apply to predators. There are few other factors which are hidden like, in our region mom control kids by make them afraid of dogs,cats and so on. This fear set in the mind of kids when they grow up. They behave accordingly.in my opinion fear is not the only reason to kill the predators. in hindrance of fear human do hypocracy. majority of people kill predators brutally for their own enjoyment & satisifaction. It's a bad thing indeed. It should be restricted
