Will Sting ever regret of not joining WWE?

Sting is the most well-known wrestler never to have worked for WWE, after he is finished with Wrestling (TNA) will he ever regret for not working for the competiton..... all his friends and his foes worked for wwe once in their lives..... i know that sting didnt want to go to wwe because he did not want to hurt his reputation , like what happened to Flair or Booker T....
