This giantess was out to punish and she did it with her giantess powers. It was super fun for her and she enjoyed all that she did to the guy and he wished that he had never crossed paths with her but it was too late. There was nothing much he could have done other than to do what she had ordered him to do. The guy did it all.
This giantess was fed up with the behaviors of this whole village and she could not continue watching them engage in those behaviors. So she had to stop it all and the only way she knew how was to crush and destroy the entire village. She managed to flatted it all and she was relieved when she was done although she asked herself whether the punishment was appropriate for the crime.
