sep3:3.Should countries leave pieces of their history out, especially that which is negative, when documenting these stories?

Countries should not leave history out of their teachings because no matter how disturbing negative or unfortunate it may be it still has altered the way we live today in some manner. Which allows us to see how the world became what it is today if we left out the bad things that happened to everyone else in the world we would be depriving ourselves of serious growth and change as a whole.
