Goddess Diana wanted to ensure that she taught this guy a lesson in obedience and that is why she did what she had to do. The mistress turned this guy into an example for the rest who wanted to disobey her. And she got her friend to help her do it and it was super painful for the guy. But that is what prompted him to make the changes he did.
This guy had been spreading rumors about mistress Gaia and she was not ok with it. He had been saying nasty things about her and she felt that to make him learn not to do that again, he had to be whipped. So she whipped the shit out of him and that is how he learned his lesson the hard way. He never messed up again after what she did to him.
Mistress Gaia found out that this guy was spying on her and she did not like it. She had to punish him and she did so using her whip. She wanted to inflict a lot of pain on him so that he would learn never to spy on her again. So she stripped him naked and she tied him upside down. She then whipped him mercilessly and ignored his cries and pleas for mercy.
