We cannot say that Dr. King Schultz is a sane person, also we cannot say that he is crazy, this is what makes him specific. Depends on a situation he knows how to behave and how to remain in peace. Dr. Schultz is an anti-slavery individual. He doesn’t follow crowd and authorities. He seems not to see any differences between slaves and normal citizens. When it comes to earn money in reward for Brittle Brothers, Dr. Schultz is able to kill anybody who stays on his way and get what he wants (typical go-getter). That’s why he kills Ace Speck.
Dr. Schultz frees Django without any major problems. He doesn’t want to take Django granted and took advantage of him. Both have an equal agreement one helps the other. There is no inequality between slave Django and Dr. Schultz. In order to indicate that Django is not a slave anymore Dr. Schultz calls him Django “Freeman”, he lets him ride a horse and behave as a regular citizen.
In a video below we can see how Dr. Schultz pours a drink for Django and treats him as a friend. Also, he is not indifferent towards Django’s wife fate and tries to help Django by stretching out his wife from Calvin Candie’s hands.
