..Again from Joseph Conrad's The Tale
What is the meaning of the word gratuitous treachery below? (And, if you have time, also the meaning of a passion of unrighteousness for its own sake)
‘What he really expected to find there was the atmosphere, the atmosphere of gratuitous treachery, which in his view nothing could excuse; for he thought that even a passion of unrighteousness for its own sake could not excuse that.
Does it mean treachery without any risk of being caught? No - uncalled for treachery, treachery that was not expected
And what about the second phrase, a passion of unrighteousness for its own sake ... I haven't got a clue about this one - for its own sake - hmm. Oh, I do so love Conrad's phraseology! I think it means that the protagonists are criminal in their activities.
