Isn't desertion treachery?

These are the words penned by the man who would become a leader of the White Rose Society, a student-led resistance movement under the Third Reich. These words have long seared their letters into my mind and soul.

My dainty, doughty little Rose,
Even though May came in accompanied by rain, all the fields were bright with the loveliest green imaginable. A sunbeam pierced a little gap in the dark sea of cloud, and the world laughed and glittered in the light of heaven. I stood there marveling and thought, Does God take us for fools, that he should light up the world for us with such consummate beauty in the radiance of his glory, in his honor? And nothing, on the other hand, but rapine and murder? Where does the truth lie? Should one go off and build a little house with flowers outside the windows and a garden outside the door and extol and thank God and turn one’s back on the world and its filth? Isn’t seclusion a form of treachery- of desertion? Things are tolerable in succession- the youthful spirit emerges from the ruins and soars toward the light- but simultaneities are antithetical, ruins and light at the same time. I am weak and puny, but I want to do what is right.

Goethe says that if a miracle occurs in the world, it does so through the medium of pure , loving hearts. That consolation has been mines since you loved me....
— Hans Scholl on 2 May 1941 - "At the Heart of the White Rose: Letters and Diaries of Hans and Sophie Scholl", Harper & Row, 2004. p.112

"Isn't seclusion a form of treachery- of desertion?" In a world where evil permeated daily life and the Reich had taken the place of an idol, there were those who sang song more lovely than those of the birds in mountain trees. They sang for justice. They died for justice. They understood that seclusion could never change the world. Hans Scholl was excecuted for treacherous activities  on 22 February 1943.
