Worried obviously, source english lit graduate, who thinks you are a mong. Also 'After' is a prepositional word.
he felt disgusted by them and thought he needed them
How Macbeth feels about the witches' predictions changes throughout the play. Sometimes he thinks they can be thwarted, as when he tries to kill Banquo and Fleance. At other times he thinks they can be relied upon. He is not sure how he feels.
Initially, Macbeth is intrigued and excited by the witches' prediction that he will become king. However, as the play progresses, he becomes consumed by ambition and starts to see the predictions as a mandate that he must fulfill at any cost. This sets him on a path of greed, deceit, and ultimately, his downfall.
Anger that his crime will benefit Banquo's family and not his own
There isn't necessarily a logical reason for the fear, but then fear is not a logical thing. Although Macbeth says, "My fears in Banquo stick deep," he is not totally clear about why he is afraid of him. Most likely, he is afraid that Banquo knows too much about him, knows what the witches said to him and how troubled he was by it, and as a result may suspect Macbeth of murdering Duncan. He is also annoyed by the prophecy of the "fruitless crown" and the prophecy that Banquo will be the father to kings. To prevent this, Macbeth would have to kill not only Fleance but also Banquo, to prevent Banquo from fathering more children. This prophecy does not threaten Macbeth, yet he feels threatened by it.

All of this makes the ball of anxiety which he feels because of the murder focus irrationally on Banquo.
at the banquet, Macbeth sees(maybe hallucinates) a ghost of Banquo, sitting in his place. Macbeth gets freaked out when he sees Banquo because all the people he ordered dead (including Banquo) makes Macbeth feel guilty.
Macbeth's world keeps on getting more and more frightening. He thought he would make himself feel safe by killing Banquo. The result was a visit from a supernatural spectre. He has no idea what to do, and hopes that the witches will give him knowledge using which he can get out of this frightening world.
Banquo is alive. Thanks, Nikki
Professional hitmen. Although with the murderers he hires to kill Banquo, he goes through the rigmarole of rehearsing their grievances against Banquo, arguably this is a sham to make Macbeth feel less like the kind of scum that hires professional hitmen to kill his friend. By the time he hires murderers to kill Macduff's family, there is no more pretence.
Yes, Macbeth is portrayed as a valiant and respected warrior before he meets the witches. There is no indication of guilt or wrongdoing in his character until the witches plant the seed of ambition and power in his mind.
To ensure the murderers will 'dispatch' (kill) Banquo, Macbeth tells them, 'Banquo was your enemy, So he is mine'. Basically, you do not like Banquo and therefore, neither do I. So I encourage you to kill him. It was very manipulative of Macbeth to say this to the murderers. He also threatens their manhood, compares them to dogs and applies various other tactics so he can feel certain they will kill Banquo and Banquo's son, Fleance.
