*spoilers*
i guess he felt that the man deserved to die, i honestly didnt understand at, it could have been that the director wanted to both gone and django starts a fight with the rest of the people on the farm, i dont know, i didnt really understand it my self either
schultz seemed like the kind of man who didnt believe in slavery, and his experience with django changed him, he could have had enough with candie once he told him to shake his hand, it seemed like shcultz didnt want to be associated with a man like candie, he didnt want to be the same type of man as he is, so when candie insisted on him shaking his hand, it could have meant to shcultz much more than just a hand shake.
honestly, you got me interested in this, waiting to hear what other people say
