You should never change erase or forget history even if its painful. Humanity wrote down everything for a reason the History of past souls are lessons to the present. Imagine a tribe way way back in time in the Amazon. There are two men in the Jungle and they find a really brite neat little frog so one man dares the other to lick the frog and his friend licks it and soon after falls dead. The other man runs to the village and writes it down Dont eat the colorful Frogs. The village then finds uses for the Frogs and knows to avoid the poison. Imagine if the man didn't want to give the frogs a bad reputation so he told nobody. History can hurt, but you learn from it. Plus erasing History can get those it involves agitated. People should respect the spirits who came before them when walking on the same ground. The Spirits are people so put yourself in their shoes. They are not things or objects of entertainment.
