In Scene 7, lines 10â12, Macbeth says "To plague thâ inventor. This even-handed justice / Commends thâ ingredience of our poisoned chalice / To our own lips. Heâs here in double trust." These lines reveal Macbethâs Group of answer choices

The correct answer is: fear of being punished for killing Duncan.

Explanation:

After deciding to kill King Duncan, Macbeth realizes that he took the wrong decision because the king treats him well and respects him. Although he knows that commit murder is wrong and insane thing to do and that he will lose his integrity, he ignores his inner struggle and decides to kill King Duncan.

When Macbeth kills King Duncan, he regrets it and becomes afraid of his evil nature and starts to feel fear of being punished for the murder because he cannot rationalize the murder of the well-loved and intelligent King.
