What characterizes someone who is "malevolent"?

The term "malevolent" is defined as having or showing a desire to cause harm or evil to others. This characterization aligns perfectly with the first option, which accurately captures the essence of malevolence. A malevolent individual is driven by malicious intent and seeks to inflict pain, suffering, or misfortune upon others, which is why having a wish to do evil is the defining trait.

The other options describe qualities that are fundamentally opposite to malevolence. Being friendly and supportive, showing indifference to others' welfare, and exuding positivity and care all reflect kindness and concern for others, which starkly contrasts with the intentions of a malevolent person. Thus, the first choice is the only one that truly embodies the meaning of being malevolent.
