When spanking ur daughter and she gets off the bed crying and rubbing her behind wat do u do?

I went to ma friend's house today but she wasn't at home no knowing she told her mom she was coming over to ma place so her mom was really upset ,she came 5 min later and when she was asked of her whereabout she couldn't speak,her mom then told me that she was going to spank her iinfront of me so she sent two of us to theo bed room and spanked her on her underwear but during the spanking she got off the bed crying and rubbing her behind, her mom got angry and started hitting her all over her body with the paddle she was using after pulled her back on the bed and continued the spanking, i felt that wasn't right was it?
