Dispose means to "throw away" or "get rid of". You dispose your garbage in a trash can. To say someone or something is disposable means it's ok to use them and throw them aside because they are easily replaced. In this context he tells his knights to dispose a human, which is a way of saying "kill them", normally when used like this it's because the one speaking is looking down on the person they want killed as if they are trash that needs disposed of or an obstacle that needs removed
'DISPOSE OF HER' that's my boy.
