Creative control can be a dangerous thing in wrestling.
If used in the right hands, it can allow a Superstar to push themselves to their very best.

In the wrong hands, creative control can be easily abused, with top stars like Hulk Hogan and Kevin Nash known for being able to book themselves as champions.
When the Hitman made it clear he was to leave the company, Vince gave Bret limited creative control for the last 30 days of his tenure, basically allowing him to decide how he would lose the title.
Out of all the options, Hart simply refused to lose to Michaels in Canada, with other plans suggested Hart forfeiting the title the next night on RAW, or losing it to someone else.
As we all know now, neither of these options happened.
