The wealthy lord should be fried for leaving his sexually frustrated wife alone for long periods of time. Besides, who the heck wants to sit and eat strawberries all day? Variety is the spice of life. And contrary to common, wt belief, there are other spices besides salt. Still, the story doesn't mention whether the princess tried to make her feelings of dissatisfaction known to her husband, so who was more negligent of the two is not discernible from what's written.
Logical hole: Since the princess was only dallying for a day, then she was only a day's journey from home and since she didn't run into any trouble leaving, why was she so concerned with what she would encounter on the way back? Plus, she was able to travel from this heinous place to her godfather's house, but she couldn't go back home?
The godfather isn't godly or fatherly. What kind of person refuses forgiveness to someone who is sincerely sorry. Of course, maybe the princess wasn't sorry for her fling. Maybe she was only sorry for the fling not turning into something more. In that case though, wouldn't the godfather want to help reunite the couple so that the wealthy lord could move on with his life? Maybe the godfather just didn't want to be bothered by mere sinners. His repugnance suggests that he probably considered himself above that kind of activity. His sins were more refined than her base sins. Off with her head!
The evil wizard is already defined as evil so he's at fault no matter what he does. The story leaves out some pertinent information though. As we learned from the seinfeld show, people have a certain level of social responsibility when they witness an evil act. So, the evil wizard may have just been following his natural instincts. He may not have been designed or created with the ability to NOT be evil. Did the godfather have the capabilities to help and just not want to because he judged the princess as not deserving help. Did he have the power to make that call.
The point I'm trying to make is that we don't have enough information to say for sure who's right and who's wrong.
