We do find repentance entertaining. One of the biggest repentance scenes in a movie is that of Darth Vader in the third Star Wars movie. And the movie clearly implies that Vader found forgiveness upon his repentance.
What if the Wicked Witch of the West in the Wizard of Oz had repented? Of course she didn't and we see the other preferred end of evil characters: death and destruction. She remained hard hearted and it led to her destruction. Consider the end of the Wizard of Oz had she repented like Vader!
We also have what I would consider the opposite of repentance in the Incredible Hulk. He changes from a mild mannered gentleman into a raging hulk of a monster! That too is a complete change in thinking and acting but in the wrong way!
Repentance means coming to terms with your past. Hard heartedness means continued denial of reality and leads to bitterness and indeed destruction. I think Vader is the better path over the Wicked Witch!
It is up to each Christian to throw off the fetters of hard heartedeness and repent! For then we shall find forgiveness and be truly free!
