23 of the most shocking, horrifying moments on 'You'

Throughout the first episode, viewers see Joe Goldberg (Penn Badgley) stalk, manipulate, and lie to Guinevere Beck (Elizabeth Lail) and Benji (Lou Taylor Pucci).

Joe's intentions are clearly negative. He lies to Benji about being interested in his soda brand and leads him into the basement of the bookstore.

But when Joe hits him with the mallet, it's clear any chance of talking things out is off the table.

There are plenty of sudden deaths on "You," but the one Benji took part in is especially unsettling.

The number of real student hazing deaths that occur makes it particularly hard to watch, in addition to the fact that Benji kept the footage of the entire incident.

Joe stalking and manipulating Beck is creepy, but the reveal that Peach (Shay Mitchell) is also obsessed with her is a new level of disturbing.

Peach had hundreds of files on Beck, and even pictures of her changing when she was underage.

This is especially alarming considering they have been best friends for years, and Beck never knew that Peach was obsessively filming her throughout their relationship.

Beck is horrified when she finds the box of trophies Joe has kept from stalking her and Candace, including her underwear, old phone, and Benji's teeth.

It gets even more chilling when Joe realizes what Beck found and goes from joking to attacking her and locking her in the cage.

Before killing Beck, Joe has only killed people he saw as obstacles to the women he is obsessed with.

After her murder, viewers realize that he may kill anyone, even people he claims to love.

This sets a precedent that everyone is at risk when Joe is around.

Joe's murdering spree throughout the first season is alarming, but his successful attempt of framing someone else for it is also terrifying.

He is able to get away with murder and ruin Dr. Nicky's (John Stamos) life and reputation.

Even when Forty Quinn (James Scully) later realizes what really happened, Joe's crimes are still never discovered.

Joe's decision to make another glass box in California shows he always knew he would need it, even though he tried to convince himself he would stop.

Since he doesn't dismantle the cage after letting Will Bettelheim (Robin Lord Taylor) out, it also calls into question who Joe would cage next.

Though Delilah Alvez (Carmela Zumbado) ends up in the glass box, he may have intended to put Love Quinn (Victoria Pedretti) there if he ever needed to.

Jasper (Steven W. Bailey) seems pretty friendly when Joe explains that he isn't the Will Bettelheim that owes him money.

Their introduction quickly turns into a horrifying encounter when Jasper cuts one of Joe's fingertips off.

The mutilation is even more disturbing when Jasper keeps the finger as a ransom for the money he's owed, leaving Joe to spend the day with a bloody wound.

When Joe kills Jasper, it doesn't come as a surprise since he can't pay Jasper back and needs to keep his identity concealed.

But Joe's method of disposal is one of the most violent cover-ups on the show.

Joe cuts Jasper into pieces, puts them through a meat grinder, and tosses the mess in a dumpster.

After Joe breaks into Henderson's (Chris D'Elia) house, he finds proof that Delilah wasn't his only victim.

Henderson's pattern of preying on underage girls is even more horrifying because he did so for years without getting caught.

Even worse, the photo evidence was in his house that party guests had access to.

The second season finally reveals what Joe did to Candace Stone (Ambyr Childers), and it's more gruesome than viewers may have expected.

His attack included tying her up, bringing her to the woods, hitting her against a rock, and burying her.

Her helplessness throughout the entire process, in addition to Joe's quick betrayal, is hard to watch without flinching.

The au pair that looked after the Quinns manipulated and sexually assaulted Forty when he was a teenager.

After Love kills the au pair to stop further abuse, Forty is left to find her body.

It's an extremely disturbing event for him considering the fact that Forty didn't understand he was groomed.

Throughout his time doing drugs with Forty, Joe sees plenty of disturbing things and remembers some dark parts of his childhood.

When he wakes up with bloody hands, both Joe and viewers are left wondering if it's real and if he killed Delilah or someone else.

Joe and his mother were abused by his father — until Joe killed him.

Discovering Joe's own father was his first murder victim is shocking, especially since he was a child at the time.

His mother is horrified and abandons Joe shortly after, making the realization sadder.

At the end of season two, it seemed as though Joe would actually be punished for his crimes after Candace locked him in the cage and revealed his past to Love.

Unfortunately for Candace, Love had no intentions of turning in the man she believed to be her soul mate.

She slits Candace's throat, leading to a quick but brutal death. It's more devastating knowing she survived everything Joe put her through.

With the help of Beck's book and a brief conversation with Dr. Nicky, Forty figures out that Joe is a murderer.

Unfortunately, no one believes him when he warns that Joe is dangerous.

Love's friends assume he's high and reaching out to Candace proves fruitless since she's already dead. Forty tries to deal with Joe himself after Love refuses to listen, only to be shot and killed by Officer Fincher (Danny Vasquez).

His death is particularly tragic since he was perfectly right about Joe and only wanted to protect his sister.

Love finds Joe's box of items he's stolen from his new obsession, Natalie (Michaela McManus).

Instead of talking to him about this or confronting Natalie with a conversation, Love decides to murder Natalie with an ax.

In a way, Love's previous murders seemed necessary to protect those around her. This slaughter was motivated by her jealousy and watching her kill someone she just met showed a more disturbing side to her.

Henry's hospitalization with the measles is an unexpected, heartbreaking arc on season three.

Thankfully, the baby ends up being fine. But Joe's fever dream showing Love wailing in grief over Henry's death in one of the bleakest moments on the series.

Joe's nightmare is unnerving and upsetting to watch, but the moment where he thinks his child is dead stands out as the most horrifying scene.

The most shocking death this season might be Gil's (Mackenzie Astin), considering the Quinn-Goldbergs don't murder him.

After realizing his son has assaulted women and his wife has covered it up, Gil dies by suicide in the glass box.

It's jarring and difficult to watch Love and Joe find Gil, and disturbing to watch them stage his death at his house.

Considering Henry's parents are murderers, it's surprising that his grandmother puts him in the most dangerous situations.

Dottie Quinn (Saffron Burrows) drunkenly drives with Henry in her lap before taking him with her to burn down her vineyard.

Thankfully, nothing happens to him, but every minute he's with Dottie is stress-inducing.

After hitting him with a rolling pin and pushing him down a flight of stairs, Love believes that Theo (Dylan Arnold) is dead.

Thankfully, he's still alive and starts to stir before Joe buried him, though he's extremely disoriented.

His severe confusion and belief that Joe was the killer, not Love, is heartbreaking.

Finally, the Quinn-Goldbergs turn on each other.

Love and Joe poisoning each other is terrifying to watch because it leaves them unable to move or even speak.

She has been harvesting the poison for weeks and even used it on her first husband, James.

Watching Joe get part of his finger chopped off by Jasper was impossible to watch without wincing.

Somehow, this is worse because Joe does it to himself and viewers can predict what he's about to do before it happens.
