why isnt sloppy butcher basekit?

Because, if you like an effect such as this and would wish for it to have it in every game, ie basekit, then its probably worth spending a perk slot on it. There are way too many call outs here on the forum, for making this and that basekit, but all this would achieve were to cement the meta even more in stone. If you got all the convenience you wish for and still got to play with all of your favorite toys, what incentive would then be there to mix things up and try something else?

Yes, there are way too many useless or dead perks, but making some of them basekit isn't the solution at all. Just look at BT! It might have been needed to turn that basekit in the camping and tunneling meta, but on the other hand, how many survivors have you seen this last month actually running BT? Maybe one or two stragglers who are returning players and who still got it in their loadouts, but no one in their right mind thinks "oh yes, 20s BT is what we need. Thats worth spending a perk slot on", everyone thinks "phew, so nice that we got BT basekit. Thats makes it a no-brainer to slot in some nice and juicy meta perk to show the killer :> ".

As much as I would love this or that perk to be basekit, Sloppy Butcher included, it just would be very bad for the game. If you like Sloppy Butchers effect, well, just equip it and enjoy survivors losing healing progress each time they run away from you. Done.

The ONLY perk that I would say could be justified to go basekit were a mini BBQ. Most people don't understand how good old BBQ was for the game health. Everyone had it equipped for the blood point bonus, but after a hook all those killers saw opportunities to the tune of "well, I actually wanted to camp this one out ... but dayum, over there in the near deadzone is a survivor hiding in the bushes" and this peeled them away from the hooks and got them into chase with someone else. Campers gonna camp and Tunnelers gonna tunnel, but BBQs dangling of an opportunity before the killers nose did more for the games health then many admit. So this were the only basekit that I would condone: after hooking a survivor, show the killer the aura of a single survivor more then 24m away. If you actually equip BBQ, you see all auras.

It also encouraged spreading hooks with the whole 'well I could go for a second hook on Kate but that 6K to 8K BP bonus dressed up like a Dwight in the bushes there looks mighty tasty.'

It’s funny that being injured is such a non-issue that the best strategy against certain killers is “just stay injured.”

In a game where fictional characters place you onto a meathook to sacrifice your abstract emotions to an omniscient omnipotent Entity in an ever-changing game of life and death, set in a place where a chainsaw wound can be healed by a minor back rub and where Legion, Trapper, and Hag all share the same level of physical strength, in a place where Jeff, Bill, David, and Meg all run at 4m/s (considering the average is 3.5m/s), where there is a eugenicist Nurse who can teleport, a writhing mass of limbs created by a cult (who can also teleport), a narcissistic doctor with lightning imbued into his heart, and realistically a victim with the ability to turn invisible by ringing a bell, you're after realism?

What if being smashed over the head with a pallet made killers slower, or swing their weapon less quickly, even for just a few seconds? Makes sense in reality, even more so for smaller killers like Legion or my beloved Piggy, but less so for hulking monsters like Trapper or Oni.

However realism has nothing to do with DBD in these matters.

Because realism does not always mean that it would be a good thing in the game.

This falls under the same category like fan favourites such as "Why dont Survivors run slower when injured?" or "Why dont Chainsaws Instakill?".

If we want to go for realism, there is a lot on both sides which needs to be changed. Like Survivors and Killers breaking their legs when they jump down from high story buildings. Or Killers being somewhat hindered by a Palletstun, the smaller ones more than the big ones. Stamina-Systems. And why exactly can this one guy turn invisible and the other girl can go through walls?!

Let alone that Sloppy Butcher is probably the most convenient Slowdown-Perk since the only investment you have is to equip a Perk Slot for some solid Slowdown.
