Having or showing intense ill will or hatred.
Example:
Captain Ahab sees Moby Dick not simply as a whale but as a malevolent, evil foe.
Malevolence runs deep. Malevolent enemies have bitter and lasting feelings of ill will. Malevolent racism and bigotry can erupt in acts of violence against innocent people. Malevolence can also show itself in hurtful words, and sometimes it can be seen in something as small as an angry look or gesture.
