Because "witches lie".
I have only recently started learning about macbeth, but i think that the three witches gain his trust by when they tell him that he is to become the thane of cawdor, he almost immediatley becomes thane. so he believes that they are actually telling the truth- hope this helps x
Macbeth is suggesting that the witches bring corruption wherever they go and that anyone who believes in them is also doomed. By aligning himself with the witches and putting his trust in their prophecies, Macbeth is essentially acknowledging his own descent into darkness and the consequences of his actions.
He continues to seek out the witches for guidance and reassurance about his future, demonstrating his trust in their prophecies. His actions in the scene reflect his continued belief in their supernatural abilities to influence his destiny. Overall, he relies on the witches' predictions to guide his decisions and confirm his ambitions.
He fears that if he pardons the prisoners, that people will no longer trust his ability to try witches.

She says, "How did you dare to trade and traffic with Macbeth in riddles and affairs of death, and I the mistress of your charms, was never call'd to bear my part or show the glory of our art?" In other words she's cheesed off that the other witches went ahead without giving her a piece of the action. She doesn't care about Macbeth or Banquo one way or the other.
