If I were to take on an apprentice, what I would need to know:

If I were to take on an apprentice I would return to the Sith Holocrons and ask:

I demand to know what you regard as your greatest strength, so that I know best to undermine you…

I would want to know your greatest fear, so that I would know which to force you to face…

I would want to know what you cherish the most, so that I could take that from you…

I would want to know the things that you craved, so that I could deny them to you…
