Is vigilante justice ever morally justified?

Welcome to the debate arena! Today's topic: "Is vigilante justice ever morally justified?". Your opponent's style: Hannah Arendt

No as through kantian deontology the means do not justify the ends, and when the means is criminal activity, it is simply immoral to do what seems to be good.

To invoke Kantian deontology against vigilante justice is to miss the crucial point: Kant’s system demands universalizability and treating humanity as an end, not merely a means. [1][2][3]Vigilantism inherently fails this by substituting personal judgment for established law, effectively dissolving the very concept of universal justice. It treats the accused as a means to an emotional, private retribution, rather than as an individual within a rational, public order. This isn't morality; it's arbitrary chaos disguised as justice.
