How do you dare to question me? You know who I am. You have seen the things I have done, so you know what I am capable of, or at least imagine that you know. Believe me, there are far worse things I have done about which you know nothing. But I think whatever you do know about should be more than enough to inform your decision about whether or not to balk at my bidding.
No? You persist in this opposition? Then you will know pain, you will learn pain such that you will wonder what it was that you ever thought to call “pain” before now. And perhaps then you will reconsider your choice to refuse my orders. And, having convinced me of your having learned this lesson, perhaps then I will let you live with your pain.
Or perhaps not. That is all up to me.
