„He who has injured thee was either stronger or weaker than thee. If weaker, spare him; if stronger, spare thyself.“
— William Shakespeare English playwright and poet 1564 - 1616
Truly from Seneca the Younger, in De Ira, Book III, Chapter V:
Aut potentior te aut inbecillior laesit: si inbecillior, parce illi, si potentior, tibi.
