Epictetus, in his work "Handbook," addresses the question of how one should deal with an enemy, particularly in terms of inflicting pain or seeking revenge. His response emphasizes the importance of personal growth and living a virtuous life instead of focusing on harming others. He suggests that the best way to "defeat" an enemy is through self-improvement and striving for a fulfilling life.

This perspective highlights a foundational principle of Stoicism: the idea that true strength comes from within and is reflected in how one chooses to live. By prioritizing one's own character and well-being, individuals can rise above conflict and negativity, ultimately finding peace in their own lives rather than seeking to harm others.
