"Pour changer le monde nous devons être bons envers ceux qui ne peuvent pas nous rendre."

Simplified Meaning:

Being kind to people who can't give us anything in return is a powerful way to make the world a better place. If you help someone in need, like giving food to a homeless person, you are making a positive impact without expecting rewards. This creates a ripple effect, where kindness spreads and inspires others to do the same. Think of it like planting seeds: when you do good deeds with no expectation of getting something back, those deeds grow and flourish, making the world nicer for everyone. For example, historical figures like Mother Teresa helped the poorest of the poor without asking for anything in return, which inspired millions of people around the world to help others, too. By being kind and selfless, we create a culture of generosity and compassion, ultimately leading to a more caring and humane society.
