Jamie killed his biological father, Garrett Randall, in the TV show "Yellowstone" to save himself and prove loyalty to the Dutton family. Garrett harbored deep resentment against the Duttons and even conspired to have them killed, attempting to sway Jamie away from the family that raised him. Jamie's act of killing his father was a drastic measure to side with the Duttons and preserve his own standing within the family, although it resulted in him becoming a blackmailed pawn under his sister Beth's control, who used evidence of the murder to manipulate him. Jamie's relationship with both his biological and adoptive families was fraught with tension, and the killing was an attempt to affirm his loyalty to the Dutton legacy despite his personal conflicts and mistakes.
