Which of the following best represents someone who seeks revenge?

The term "vengeful" precisely captures the essence of someone who seeks revenge. It describes a person who has a strong desire to inflict harm or punishment on someone in response to a perceived wrong or injury. This desire for retaliation is indicative of a mindset that is focused on retribution rather than reconciliation or forgiveness, which is key to understanding the nature of revenge.

In contrast, a pacifist advocates for peace and non-violence, actively avoiding conflict rather than seeking to settle scores. Diplomatic individuals typically strive for negotiation and compromise to resolve disputes, which stands in stark opposition to the vengeful attitude. A compromising person also seeks to find middle ground and avoid confrontations, further distancing themselves from the desire for revenge. Hence, "vengeful" is the most accurate descriptor for someone motivated by the urge to seek retribution.
