What do you think should be better in books?

What do you think should be better in books?
I think for example a blind/deaf main character or something like that

The main character is almost always the hero, defeats the villain etc.
So better things in books could be if the main character for example wasn’t the good person or died or something.

So if you or anyone else have some ideas to what there could be better then feel free to write it here!
