"Stars, hide your fires; let not light see my black and deep desires." - Macbeth, Act 1, Scene 4.
Macbeth, before the murder, can never fully reconcile his desire for the throne--which is strongly encouraged on, if not coerced, by his ambitious wife--and the murder of an old man, a man who has been supportive and generous towards Macbeth, who has never used or abused Macbeth in any way. Macbeth daydreams of being king, but is afraid of the steps towards it--a brutal murder, falsely accusing the retainers in the king's death, the possibility that he will no be believed by his peers. Regicide is a crime, but it is made more terrible when the man killed was a good and just mentor undeserving of the act.

Macbeth’s ambition to become king
The "black and deep desires" he is talking about is the temptation to hurry along Duncan's death so he can become king quicker.

The temptation is to help the prophecy along.

Macbeth was consumed by his ambition and desire for power, leading him to prioritize his own goals over his moral conscience. He was influenced by Lady Macbeth and ultimately convinced himself that the benefits of committing the murder outweighed the voice of his conscience.
"The Prince of Cumberland! That is a step on which I must fall down or else o'erleap." The idea was that the Prince of Cumberland was the heir apparent, like the Prince of Wales in England.
