Context: The Inquisition, by defining and limiting knowledge, was evil. The Taliban, by defining truth and refusing girls an education, is evil. Any religion that says it knows the one and only truth is evil, because it limits knowledge. Any political body that says it owns the truth is evil. Same reason.
Any repressive regime that seeks to control exploration and experimentation is evil. Same reason. Any regime that defines truth as a set of beliefs and occurrences that cannot be questioned, that can neither be demonstrated nor proven is not only evil but ridiculous. This includes all mythologies, miracles, etc. because, if creation happened for a reason, if it was done by God, you'd better believe every part of it, including intelligence, was done for a reason ascertainable, eventually, by intelligence. We would not follow and adore a ruler who lied and tortured. Why would we worship a God who did either? God doesn't lie and he/she/it doesn't fool around!
Shutting down inquiry is evil. Causing pain purposefully for no reason is evil. Enjoying causing pain by shutting down inquiry is an absolute evil.

Attributed to Bonhoeffer on the Internet, and supposedly from Bonhoeffer: Pastor, Martyr, Prophet, Spy http://books.google.com/books?id=aG0q3X8TVpsC&pg=PA486#v=onepage (2010) by Eric Metaxas; however, there is no actual reference in that book. However, in advertising the book Metaxas does state on his site that the quote is from Bonhoeffer. http://ericmetaxas.com/books/bonhoeffer-pastor-martyr-prophet-spy/ First attributed to Bonhoeffer in Explorations 12:1 (1998), p. 3, as referenced by James Cone (2004) Theology's Great Sin: Silence in the Face of White Supremacy, Black Theology, 2:2, 139-152, footnote 1 http://dx.doi.org/10.1558/blth.2.2.139.36027
Compare "Not to Act, is to Act!" by Francis W. McPeek http://www.ergo-sum.net/pics/McPeek.jpg, The Missionary Herald at Home and Abroad, v.141-142 (1945-1946), "Missionary herald, 1945 - Congregational churches," pp.34-35 (We must realize that church inaction is a form of political action, and it is altogether negative. “Not to act, is to act.”)
