Leo Tolstoy said this quote

To destroy the life that dwells in othersis beyond your power. The life of those you have slainhas vanished from your eyes, but is not destroyed. Youthought to lengthen your own life and to shorten theirs,but you cannot do this. Life knows neither time norspace. The life of a moment, and the life of a thousandyears: your life and the life of all the visible and invisiblebeings in the world, are equal. To destroy life, or to alterit, is impossible; for life is the one thing that exists. Allelse, but seems to us to be.
