Both humans and others love to pursue power and money, and it's never-ending. The dwarves who live rich and happy, using their wisdom and labor, live a happy and free life, but all this is ended by more and more wealth.
The discovery of the Heart of the Mountain made the dwarven king Thor more and more morbid about wealth, and finally one day attracted the attack of the dragon, who also had a fanatical desire for gold, it could not mine, it could only plunder, its arrival, the life of the dwarves was completely destroyed, from a free and happy person to a person who had no place to live, wandering around.
Compared to them, the Barkins Hobbit was simply too happy, because he had his own home, could enjoy every delicious meal, if that morning, he did not sit in the doorway and enjoy the beautiful sunshine, if he did not meet the person who changed his life - Gandalf, perhaps his life is no different from other hobbits, and he will live a life in peace.
Perhaps Baggins himself could not have imagined that everything had changed in the moment he met Gandalf, imagine what you would choose if you were preparing to enjoy your own dinner, and suddenly the doorbell rang, entered someone you had never met, came to mess up your room, snatched your food, and invited you on an adventure with you. Do you choose to turn a blind eye or follow your heart? Perhaps there were already choices in Baggins's heart, and the unknown journey awaited them.
Originally life is an unknown journey, but no matter how far you go, you will miss your home, because home is behind, the world is in front, but for Thorin, they are now homeless, because their home, at the time of the dragon invasion, is gone, in order to be able to go home, no matter how difficult the road ahead, must move forward, because Thorin wants to take back his home, and to protect it.
Because of Thor's greed, Thorin lost his home, lost his relatives, and also because of greed, Gollum changed from a normal person to a person who is not a noble ghost, and can only live in the dark, never day. He could only keep the ring that made him more cruel and greedy.
Maybe we don't think it's worth it to lose our freedom or even lose our lives for the sake of the gold and the Lord of the Rings, but we're not Thor or Gollum, and we don't know what they think.
In order to be able to go home, Thorin and Baggins from the beginning of mutual distrust to the end of the affection, they have been too difficult to go this way, Gandalf in order to adhere to their ideals, all the way to accompany. On the way to adventure, with so many good friends in the company, Sorin is also happy.
The way home was in front of them, but there was more danger waiting for them inside. Greed destroys everything they have, and it is hoped that when the door opens, Thorin will be able to overcome greed and take back everything that belongs to him.
