"Voir ce qui est juste et ne pas le faire est un manque de courage."

Simplified Meaning:

When you know the right thing to do but choose not to do it, it means you are being afraid or lack the bravery to act. Imagine you see someone being bullied at school. You know it’s wrong, and you feel like you should help, but instead of stepping in, you stay silent because you're scared. This happens because it takes courage to stand up and do what's right, especially if you're worried about what others might think or if it might cause trouble for you. Having courage means overcoming that fear and acting anyway because it's the right thing to do. For example, in history, civil rights leaders like Martin Luther King Jr. knew it was right to fight for equality even though it was dangerous. They showed great courage by taking action despite the risks. If you want to follow this advice, you can start by practicing small acts of bravery in daily life, like helping a friend in need or speaking up when someone tells a harmful joke. Over time, these small acts build up your courage to handle bigger challenges.
