If by evil you mean irrational hatred then yes, we have been visited by that most unspeakable evil. In the same moment we have witnessed unimaginable good in the face of such disregard toward the sacredness of life. Clearly within us lies this dichotomy. When we chose fear over love all mankind suffers. When we chose love over fear the world's broken heart is mended.
L'amour pour Paris. Paix pour le monde. Nous sommes tous un seul people.
