Milan Kundera said this quote

But it was not only a feeling of guilt which drove him into danger. He detested the pettiness that made life semilife and men semimen. He wished to put his life on one of a pair of scales and death on the other. He wished each of his acts, indeed each day, each hour, each second of his life to be measured against the supreme criterion, which is death. That was why he wanted to march at the head of the column, to walk on a tightrope over an abyss, to have a halo of bullets around his head and thus to grow in everyone's eyes and become unlimited as death is unlimited. . .
