Why did the Montreal screw job happen?

The Montreal Screwjob occurred during the 1997 Survivor Series event due to tensions between WWE owner Vince McMahon and Bret Hart over Hart's contract situation. Hart was set to leave WWE for WCW but wanted to retain the WWE Championship through his final match. Fearing that Hart would not drop the title as planned, McMahon, in collusion with certain officials, orchestrated a controversial finish where Hart was pinned without his consent, leading to a significant fallout in Wrestling history. This event highlighted issues of trust and control within the wrestling industry.
