I think the sentence that uses it correctly is the last one.
Answer: As this is an opinion, I will say Macbeth.
Explanation:
Macbeth proves to be more evil than Lady Macbeth.
1. While she plays a very devious role as inspiring him to commit the deeds of murder, in the final analysis, Macbeth is the one to commit these acts.
2. While Lady Macbeth does display some level of regret, guilt, or remorse about her actions, Macbeth plunges into a deeper moral abyss with his actions and the depravity they represent. Both characters can fit the label of being evil with their actions and thoughts, Lady Macbeth still had the ability of compassion or even empathy that Macbeth did not possess.
