The moral could be about the importance of using resources wisely. For example, if the man in the story was wasteful with the wood, it might show that we should not be extravagant when dealing with nature's gifts.
The main character is the man. He is the one who has some kind of interaction with the wood, whether it's cutting it, carrying it, or using it for something.
The moral could be about acceptance. Just as the crooked man was different in appearance, it might teach us to accept those who are not 'perfect' in society.
The moral is that different perspectives matter. Just as the man and the lion in the story had different views on who was stronger based on their own positions. It shows we should consider multiple viewpoints.
The moral could be about hard work and preparation. In the story, perhaps the man had to carefully handle the wood, showing that we need to be diligent in our tasks. Just like in real life, if we want to build something with the wood (metaphorically achieving a goal), we have to put in the effort to cut, shape and use it properly.
The most prominent character is the crooked man. He is the one around whom the story is built. In some interpretations, there could be an antagonist, perhaps someone who discriminates against the crooked man because of his appearance. But overall, the focus is on the crooked man and his experiences in the fable world, whether it's about how he copes with his situation or how he changes the perspectives of those around him.
The main character is the man. He is the one who has a relationship with the wood, whether he is cutting it, using it for building, or some other activity related to the wood.
