What does the person talking to Priscus mean when he says and ldquoThe climax of misery is to have to pay ... for justice?

The speaker suggests that the ultimate form of suffering is having to financially bear the cost of seeking justice. This implies a deep frustration with a system where justice, ideally a fundamental right, is commodified and accessible only to those who can afford it. It highlights the inequities in the legal system, where the pursuit of fairness becomes a burden rather than a guarantee.
