A Robin becoming the Joker is a storyline that appears in specific alternate universes and stories, not in the main DC Comics continuity. The reasons for this transformation vary by the story in question:
This happened in one of the deleted scenes of 2022's The Batman, and Keoghan's version of Batman's nemesis was as absolutely horrifying as it could get.
Keoghan appeared in Matt Reeves's film The Batman (2022), credited as "Unseen Arkham Prisoner", a character subsequently confirmed to be the Joker.
The chemical bath triggered a chemical imbalance in Jack's brain-chemistry which resulted in him becoming the violent and sadistic criminal known as The Joker.
Despite both characters being hyped up as super crazy, neither is usually portrayed as all that crazy. They're both pretty aware of the world around them and their own actions.

In Joker, Thomas Wayne (Batman's father) and Penny Fleck (Joker's mother) are key characters. Penny claims that Thomas is actually Arthur's father.
Reeves said that this Joker was born with the disease that makes him unable to stop smiling, but this disease does not explain the green hair (and lack of hair), the white skin, the burns on his hands and face, which leads me to believe that he's hiding something about this Joker's origins.
In Joker's case, pseudobulbar affect probably occurred secondary to severe traumatic brain injury (TBI). A number of studies have established that TBI increases the risk of mood disorders, personality changes and substance use disorders.

Ben Affleck didn't get his solo Batman movie due to a mix of creative differences, personal struggles (including alcohol addiction), and the troubled production of Justice League, which made him realize the immense pressure wasn't worth it, leading him to step away from writing and directing the film. He couldn't align his darker, grounded vision with Warner Bros.' plans for the wider DC Universe, and ultimately decided he wasn't the right person to make the film he wanted, passing the torch to Matt Reeves and Robert Pattinson.
Talking about getting the role, the Irish actor said that he got the gig by completely improvising his audition tape. Detailing this, he said: “The Joker, that was funny how that happened. I just made it up. I wanted to make it Kubrick-y: symmetrical, the X on the back, the square doorframe, everything square.

While she cares about her son, she has shown to lie to him multiple occasions which leads to her death. Despite seemingly being kind to Arthur, it later transpires that she gossiped behind his back and scoffed at his idea of being a comedian and his notion that he was in the world to bring joy and laughter.
He lived with his mother Penny Fleck, who had possibly adopted him. Enduring his abuse, Arthur was found tied to a radiator, bruised and malnourished; he suffered severe head trauma that was believed to have caused him to have his uncontrollable fits of laughter.

Yeah, that one… Posting on social media, David Ayer (who had previously helmed Fury and Sabotage by the time he landed Suicide Squad) said he wishes the Joker's forehead tattoo, which reads Damaged, said something else entirely, as the one we all know – and mostly hate – only split audiences.
