Many people have never heard of the battle that went on in the heart of the Shire itself, due to the fact that it wasn’t in the movies. In fact, Saruman never died in Isengard, instead, he was let go and eventually made his way to the Shire, where he took over.
When the four Hobbits; Sam, Frodo, Pippin, and Merry, got home after the war ended, they found that the Shire was under new management. Though they didn’t know at the time that Saruman himself was responsible.
Most of those who know of the Scouring thought that it was a slightly unnecessary, anti-climactic ending to a story. However, when you look at it, it is incredibly symbolic. It shows that even the most pure and homely place can be touched by evil. You aren’t going to be safe simply because you are in your home. Temptation reaches you anywhere you are.
The Shire had always been a place where Frodo and Bilbo were able to relax, with no worries of anything outside of their home. To make things worse, Saruman was staying in Bag End, as if Satan himself was taking up residence in his home. They even chopped down Bilbo’s tree (which could possibly be the tree that grew from the acorn Bilbo picked up from Beorn’s garden. 😉 ).
In the Lord of the Rings movies, the Scouring was represented when Frodo looked into Galadriel’s mirror. Peter Jackson wanted that aspect of evil reaching everywhere by showing the scene with hobbits in shackles.
When the Hobbits finally discovered that Saruman was the “Chief,” Frodo was going to let Saruman go, despite all the disapproval of all the other Hobbits. Frodo became a benevolent leader, thanks to all the examples around him and the near death experience that defined him. Even though Frodo forgave and let Saruman go, he soon after met the consequences of the things he did.
Frodo showed that forgiveness, even to people who have robbed, killed, and destroyed, is not impossible. We are asked to forgive everyone, and let God forgive whom he will forgive. He is the only one who has the power to judge us, because He knows our hearts and our intentions.
After Frodo said many times more sure than ever, Saruman cursed him for the mercy he gave him, then proceeded to mock Wormtongue and accuse him of murders that Saruman forced him to commit, Wormtongue killed Saruman himself, just like in the movie. And was then shot with an arrow, again like the movie. It shows that if you let the devil rule your life, you can almost never come back. You still have the option of repentance and mercy, but if you become bitter against the devil instead, you are only harming yourself. As I have said many times before, having anger against someone is only hurting you. Plus, Satan wants you to be angry, you are only doing what he wants by hurting others. Then you are dragged down with him.
This scene was a very important aspect in the book, but the movie still did a good job of adding in the messages, even if they didn’t do so in the most accurate way. Either way, they were both told wonderfully.
