Ok fine, I'll explain more. They explain in the opening narration that when humans were first brought into creation, they used their ingenuity to help make a future for themselves. However the Grimm began attacking humanity and drove them to the point of extinction. It wasn't until humans discovered how to use Dust that they were able to fight the Grimm and eventually protect themselves from them well enough to build the world we see in the series.

However just because humans have advanced over however long their history has lasted, doesn't mean that the Grimm ever stopped trying to kill them. In fact during the initiation ceremony at Beacon, pretty much all the main cast were attacked by Grimm. Some could have been provoked, like the Death Stalker and Nevermore, but the Ursa that attacked Yang and the King Taijitu that attacked Ren seemed like unprovoked attacks.

To explain even more, the Hunters don't attack Grimm because it is fun. I would also like to point out that I am not included in the "we" you mentioned that think killing animals for sport is fun. Also if you think killing people is "FUN," you should probably get some help. Back on topic however, Grimm aren't pests and they aren't just defenseless animals out in the wild that people hunt for sport. They are very dangerous animals with an urge to kill anyone near them. It would be like if you had a pack of wolves around your house, but instead of leaving you along like most real world wolves would do, these Grimm-wolves try constantly to break into your house and eat you all the time. So Hunters step in and kill them because they are dangerous and pose a threat to you.
