Final answer:
The pursuit of justice by Wargrave, even when seeking to punish the guilty, does not justify the act of murder as it undermines the rule of law and the judicial process that defines a civilized society.
Step-by-step explanation:
The debate over whether Wargrave's seeking justice justifies the murders is complex and on one's definition of justice and the moral implications of taking the law into one's own hands.
The idea of justice being served through extrajudicial killings is highly controversial. In literature and in real cases, like the vigilantism for perceived justice in the case of Dr. George Darden, such acts raise difficult ethical questions.
Individuals like Wargrave taking on the role of judge, jury, and executioner outside the established legal framework conflicts with the rule of law. The societal consensus generally falls on the side that while the desire for justice is understandable, it does not morally justify murder.
In none of these scenarios, whether it be the historical acts of the Paxton Boys or the fictional acts of Wargrave, is the usurpation of the judicial process seen as a legitimate form of seeking justice.
