Historians have a word for Germans who joined the Nazi party, not because they hated Jews, but out of a hope for restored patriotism, or a sense of economic anxiety, or a hope to preserve their religious values, or dislike of their opponents, or raw political opportunism, or convenience, or ignorance, or greed. That word is "Nazi."

Historians study their motives, but there is a broad understanding: their motives don’t exonerate them.

@JuliusGoat Strange, given that 'intention' forms the basis for many sound judgements.

@Kanchana Not so strange, really. Just because intention can form the basis for sound judgements doesn't mean that it can't also form the basis for unsound ones.

And deeper intentions than those we admit are revealed by our actions and alignments.

@JuliusGoat Hmm...Motives may not exonerate, but certainly play a role in categorisation / sub-categorisation of people in the myriad shades of black, yes?
