things would be different if considered at a different point of view

After reading "From Bury My Heart at Wounded Knee", I realized that there is nothing absolute right or wrong because the judgment is made upon a certain point of view and things would be different from what they are original thought of if considered at a opposite point of view. For example, the history we are taught is generally thought to be absolute right with no doubt. However, if considered deeply, there might be plenty of doubts about things we have learned.
People have been taught when they were children to have a basic thought about what is right and evil. As time goes, the children grow to be adults and start to look at things wisely. Something which is commonly thought to be wrong and abandoned does make sense in other field. The history is no exception. History is written by the winners and surely all that have been written in the book is saying good about the winners and bad about the losers. Like the China community, according to the Chinese history book, there is nothing written about what evil things committed by the China community but a whole bunch of nice and beauty things accomplished by them. Born and growing up in China, I have never thought the China community to be anything wrong until I was taught in high school, but I never blame on them for not allowing children to know the truth. Instead, I understand and strongly agree with them about doing so. By all means, they are the winner and they have the right to make all people obey them by impressing their people with good imagines.
All in all, everything exists in two sides, depending on which point of view it is looked at. Winners can write the history in a way they like and so do losers.
