When Rick and Morty first premiered on Adult Swim, Rick's daughter Beth was portrayed as a smart, no-nonsense mother who loves her family more than anything. Three seasons in, and it's becoming clear that she might be far less put together than she likes to believe. This confident horse surgeon might be a sociopath as demented as Rick, which is certainly saying something.
Rick's relationship with Beth has been one of the series's more emotionally charged plot lines, dealing with issues like childhood abandonment and alcoholism. From the first episode, it was made clear that Rick was just coming back into his family's lives after being estranged for years, and that he's only recently started to heal those relationships. But it might be too late for Rick because Beth's history indicates that she may already be too far gone.
This list of compelling evidence – which includes quotes from Rick and Morty – should be more than enough to convince fans that Beth Smith is messed up, with or without Rick.
In "The ABC's of Beth", Rick paints a pretty terrifying image of Beth as a little girl. "You were a scary f*cking kid, man," Rick says to his daughter during an argument. He was so worried about her dangerous potential, he invented the magical world of Froopyland to "protect the neighborhood."
Without that distraction, it sounds like she might have let her sociopathic tendencies wreak untold havoc among the townsfolk.
It's easy to blame Rick's absentee parenting and debilitating alcoholism for Beth's emotional issues, and that's exactly what she does in "The ABC's of Beth." She refuses to apologize for herself and instead puts it all on Rick, who even admits to being a horrible father.
But even after accepting his share of the blame, he makes it abundantly clear that he believes a lot Beth's murderous rage and twisted thoughts are on her. Most of the morally questionable things he did for his daughter, like building her a taser shaped like a ladybug, were a direct response to her nightmarish requests.
During that same argument, Rick offers up a throwaway line that may hold extremely dark implications. When he explains his motivations for building Froopyland he says, "It was just more practical to sequester you before I had to start, you know, cloning a replacement for every less than polite little boy or gullible animal that might cross your socio-path."
Rick isn't just improving here, it sounds more like a disgruntled man speaking from experience. If what he's saying is true, that means Beth has likely hurt innocent children for being "less than polite," to the point where Rick actually got tired of cloning and replacing her victims.
Young Beth clearly has no qualms with killing, or at the very least horribly maiming, both people and animals who cross her "socio-path." One of the items that young Beth requested from Rick may have been a reference to her eventual career as a horse surgeon.
She displays a morbid curiosity of anatomy from a young age, prompting her to ask her father to build her a teddy bear with "anatomically correct innards." Beth is giving off a serious Dexter vibe here, possibly working her way into a job that allows her to fulfill her thirst for blood and gore.
