Final answer:
Lennie inadvertently harms or kills when he panics, a theme demonstrated vividly in Steinbeck's 'Of Mice and Men' where his unintentional actions have devastating consequences.
Step-by-step explanation:
When Lennie panics, he unintentionally harms or kills as a result of his physical strength and lack of control over his actions. This pattern of behavior is seen when he unintentionally kills small animals by petting them too hard, and most tragically, when he accidentally kills Curley's wife in Of Mice and Men by John Steinbeck. Lennie's panic-induced responses exemplify a theme of the unintended consequences of one's actions despite intentions, often highlighted in literature through various means such as hyperbole, sensory detail, and dramatic actions. An instance of this occurs when a character experiences a moment of panic and, in fear and confusion, ends up causing harm due to a reactionary impulse.
