Jamie Dutton's grief on "Yellowstone" affects actor Wes Bentley in his daily lifebut the character's existential travails are understandable. After all, Jamie killed his biological father, lost both of his adoptive parents, and never got to realize his childhood dream of becoming a rancher (he became a lawyer). However, it doesn't help that his sister Beth Dutton (Kelly Reilly) is relentlessly hostile towards him during every conversation they have. So what's her deal?

Some people argue that Beth is a sociopath whose treatment of her brother is unfair, especially since she singlehandedly encouraged him to kill himself in the Yellowstone season 2 episode "Resurrection Day" because he was emotionally vulnerable after murdering an innocent journalist in cold blood. . However, Beth probably has valid reasons to hate him, stemming from an incident in their teenage years that essentially ruined her chances of ever being truly happy.

Since then, Jamie's actions have given Beth more reasons to hate him, and some of the concerns she has about his loyalty to their family have unfortunately come true. With that in mind, let's examine all the reasons behind their bitter feud.

This is the root cause of Beth Dutton's hatred of her brother, dating back to their teenage years. It all started after she got pregnant and asked Jamie to help her get an abortion, so he took her to a free clinic outside of town and sterilized her without her consent.

Beth's anger at Jamie intensifies as "Yellowstone" progresses, especially after she decides to settle things with Rip Wheeler (Cole Hauser) once and for all. Beth fears that her husband will never feel fulfilled in their relationship because she will never be able to give him a child, and she carries some guilt over the abortion because the teenage Rip was the father but didn't know it at the time.

What's more, Beth learns about Jamie's own son in "Yellowstone" season 5, which causes more feelings of animosity towards him. She then tells him that he doesn't deserve to be a father and threatens to take everything he wants from him, though it remains to be seen if she meant to forcefully adopt his child or commit a heinous act on the child.

Contrary to some people's beliefs, Jamie Dutton wasn't always bad news. As the family's lead attorney, he once did everything in his power to serve their best interests, even when they deserved to go to jail. However, their relationship sours after family patriarch John Dutton (Kevin Costner) destroys Jamie's political ambitions by running against him to become governor of Montana. This led to Jamie spilling all the dirt about his family to a reporter, who he later killed to ensure the story wouldn't get out.

Beth hasn't trusted Jamie since the aforementioned spay incident, but finding out he cheated on their family puts another nail in the coffin for their relationship. Furthermore, Jamie has suggested that the family sell some of their land to ensure they remain financially comfortable (and to boost his political prospects), so Beth sees him as a threat to their way of life, especially after calling him out John to be impeached as he secretly works alongside the people who want to stop them. This wacky family, isn't it?

However, Beth may have a point about Jamie being untrustworthy. In addition to shooting his original father, he is partially responsible for death of John Dutton — and anyone who watches Yellowstone knows that Beth is a daddy's girl through and through.

Jamie is partially responsible for John Dutton's death in Yellowstone Season 5. His lover, Sarah Atwood (Zora Olivieri), hires assassins to take him out of the game and make it look like suicide, and Jamie more or less supports her decision after she comes clean to him about it. That said, he initially mourns his father, proving that Sarah acted of her own free will and exists some humanity remained in Jamie.

Of course, Beth immediately suspected that Jamie was behind her father's murder from the moment she found out he was dead. John's death angered many Yellowstone fans.but that's nothing compared to the anger Beth feels towards her brother. She vows to kill her sibling, but her other brother, Case Dutton (Luke Grimes), convinces her to hold off until they have proof.

Eventually, they learn that Jamie was involved, so Beth raids his home, buries a knife in it, and forces Rip to dump his body in the "train station"—which is really an out-of-state canyon that houses all the skeletons. in the Dutton family closet. What's more, Beth told the cops that Jamie attacked her and went on the run, ensuring that she also ruined her brother's reputation in the public eye, as the news broke the story afterward. If Jamie lost his sound rep, it would upset him more than getting stabbed, so Beth got the last laugh.
