After playing this game for over 200hrs, both as Survivor & as Killer, I've been around many survivors who just know better than both you & me, on how to play this game as killer. What I'm giving you today, is the guidelines to the Survivor's perfect Killer. Be warned though, the guide may contradict itself in a few places because each Survivor has a different opinion of perfection. They're like Borg Drones without the Collective Hive Mind.
(And yes, these are all excuses that I've come across whilst playing the game)!

This is self explanatory really. Every Survivor is different, but 99% don't like to lose & they also want to do things in the game, like challenges or achievements.
They certainly don't like it when you have a mind of your own & actually do Killer things.
So basically, go against natural instincts & do everything they want you to do instead, especially if they're trying to get your attention.

You see, focusing on a particularly easy survivor is frowned upon because it makes it harder for the survivors to escape, since there'll be less people working on generators, and also one less meat-shield for taking protection hits. Thus, you're not allowed to tunnel or camp them, or risk being called a big saddo.

So, lets say the survivors have managed to 3Gen themselves in a corner of the map.
God forbid you do the most logical thing & patrol them, preventing survivors from repairing those gens.

What if you actually patrol the gens? Well, the survivors will definitely attempt to repair them. If you manage to down & hook (Or Mori) any survivors going for these gens, they'll claim you're tunnelling / camping them. Since that's also Rule #2, it's a big no no. The next most logical thing to do is to just let them repair it & leave.

Survivors like an easy ride, one without challenge, one they can just coast by in.
They certainly don't like it when the killer brings perks that prolong the game or give the killer an extra advantage, like HEX: Ruin, No One Escapes Death & No Way Out.
Or Perks that may hinder Survivor abilities, like Lightborn & Franklin's Demise.
Or any perk for that matter.

Pretty much any perk that is useful to use as a killer, the survivors won't like at all. Because from their point of view, it's just a bag of unsolicited AIDS, so you're better of not bringing any at all.

Survivors love looping killers, so when you come across a dropped pallet, don't break it, just keep getting looped until the endgame.
You should also avoid damaging any generators you come across too, there's just no need for a killer to do that.

Don't use common sense. Better yet, don't use your brain.
You see, some survivors will accidentally blow up a generator, but be lucky enough to be really close to a closet to hide in. If you've come to that generator really quickly and you don't see any scratch marks leading away, whatever you do, you're not allowed to check the closets. If you do and you find a survivor, they're liable to call you a big bad cheater.
Scary, right?

This goes for pretty much anything, like predicting movements in chases, tricking your opponent into making a mistake or preemptively dropping a pallet. Best solution is to just stop using your brain when playing as killer.

Tying into Rule #1, Survivors love friendly Killers. This allows them to get achievements & challenges done a lot easier.
So, be AFK, or just don't use your attack buttons whenever you're in striking distance. Simply be like a lost dog.

Say, have you given up playing as the killer for this round?
Do you just want to gain some extra bloodpoints instead, while you wait for survivors to leave, because you know you're not going to win?
Well you're not allowed. You see, that's not playing the game normally & some survivors don't really care if you let them leave or not, they just want you to play the game normally. So, don't bother farming Bloodpoints, just run around when your hearts not in it. This also ties into Rule #10.

Add-ons are just plain Illegal & shouldn't be a part of the game, obviously. Nobody likes an Infinite Tier 3 Michael Myers or Nurse who can do a third blink.

As for offerings, the only one you're allowed to bring is Bloody Party Streamers so those Survivors can gain extra Bloodpoints! Any others are, as you guessed, also illegal.

Nobody likes it when you rage quit. It stops certain things from progressing, limits the amount of bloodpoints that Survivors are able to gain and generally wastes time.

Anything you consider to be fun, the Survivors definitely don't. So simply stop having fun.

You knew this was gonna appear at some point in this guide.
Basically, don't use your tail attack as Xenomorph, don't stalk as Myers, don't throw bottles as clown. If your killer has a special ability, don't use it.

Probably the most illegal & heinous act you could possibly commit whilst playing as killer.
Winning! You're definitely NOT ALLOWED to win. If you do, survivors will throw all of their toys out of the pram.

They'll call you & your family stinky. They'll say you're an unloved child. Basically, any insult under the sun, they're gonna end up calling you it. The most famous in this game is obviously KY5, you know for a fact that when that one comes flying at you, they're basically streaming tears of salt at this point.

Have you come across a ridiculous thing that a survivor has said, that you believe should be shared in this guide? The comment section is open, feel free to share with the community!

Hopefully this guide has given you some insight into how survivors wish their killers would act.
If you found this guide helpful, funny or down right accurate, consider rating it up & adding it to your favourites. If you're feeling particularly generous, I'd truly appreciate an award (even if it's a Jester, all awards are appreciated).
Good luck with your games!
