#2 Heart Family Betrayal
Bret and Owen Hart may have been the greatest sibling duo in the history of professional wrestling. Which is why WWE was smart to turn it into a long-standing feud between the two best wrestlers of the Hart family.
Owen was frustrated with Bret for screwing up a Survivor Series match that got Owen eliminated. In part, Owen was also slightly jealous of how well his brother’s career was going and how his own didn’t seem to be going in the same direction. Owen would then leave matches, abandon his brother. He also thought Bret always craved the spotlight when they wrestled together.
Bret tried making amends when they fought in tag team match together at the Royal Rumble. But Bret had kayfabe hurt his knee during a match, and the ref stopped it, only for Owen to snap and brutally attack his brother. Owen became a heel after this and the full backstabbing to his brother had been completed.
