Another Amfas analogy

I normally think about A Man For All Seasons when the question of how effective the law is at establishing justice.
But today it's the latest round of ideological purity tests that made me think of it.
Sir Thomas fought as hard as possible to keep his faith and his friend, and lost his head in the process.
His family suffered for a principle of his they couldn't fathom.
While parroting all the right words wasn't enough to save Cromwell, regardless of how truly he believed.
And only the pathetic liar Rich made well in the end, for given values of well.
Depressing as fuck, but I can't really shake it.
