To be obedient and loyal to any modern group (institution, corporation, church etc.) is expedient, and to lack courage: to be on-the-side-of evil.
Courage must therefore be individual, goes unrewarded (or is often punished) by society and social institutions; and the needful courage is cold rather than hot.
(Hot courage is short-term, unthinking and in the heat of the moment. But cold courage is considered, long-termist and must strive-against against the continual pressure of unrelenting opposed expediency.)
