Why are Wiesel's efforts to share his experiences during the holocaust with as wide audience as possible important?

Hope it helps :)

Explanation:

Nobel laureate and Holocaust survivor Elie Wiesel, whose death at the age of 87 was announced Saturday, summed up his mission in 1986 when accepting the Nobel Peace Prize: “Whenever and wherever human beings endure suffering and humiliation, take sides. Neutrality helps the oppressor, never the victim. Silence encourages the tormentor, never the tormented.”
