What term describes a person who is spiteful and vindictive?

The term "vindictive" accurately describes a person who is spiteful and seeks revenge or holds a grudge against others. This word encapsulates the intent and emotional disposition of someone who not only feels wronged but also is motivated to retaliate or cause harm in response to perceived injustices.

In contrast, the other terms present different qualities: "generous" refers to someone who is willing to give more than is usual or expected, "forgiving" describes a person who is inclined to excuse or overlook the mistakes of others, and "compassionate" pertains to someone who shows empathy and concern for others' suffering. Each of these alternative choices reflects positive traits that are fundamentally opposed to the negative attributes associated with being spiteful and vindictive.
