Choose the perspective from someone from north or south. was the civil war necessary?

In my honest opinion. I believe the civil war was not necessary. Seeing the war from the north view. There should not have been a war, the civil war was over many things including human rights for poc (people of color). Everyone is equal and fighting over someone as if they are a object instead of a person is ridiculous. The south needed there slaves. The north fought to end slavery and preserve the union. Lincoln was focused on freeing the slaves and keeping the union. Nowadays people are changing history saying Lincoln was not for freeing the slaves but if you do your own book research instead of internet research you will see he was very big about freedom.

No because we could have agreed on not having slavery
