are u seriously making a parallel between taunts in the act of battle (u know that thing u do to get in your opponents head to gain an advantage) to a guy who finally let his guard down and exposed that the image he purports is false?
Not the greatest comparison but the point is people do things out of character or that they may regret during competition. Anderson acknowledged he went beyond getting in Maia's head and knew he crossed a line, that's why he begged forgiveness from Maia.
