Analyzing Author's Tone in Historical Context

The following passage is an excerpt from a historical analysis of political revolutions:

"Throughout history, revolutions have often been portrayed as noble struggles for justice and equality. However, a closer investigation reveals a more nuanced reality. While many revolutionaries undoubtedly possess a fervent desire for change, the outcomes frequently deviate from initial aspirations. In some instances, power merely shifts from one oppressive regime to another, leading to cycles of violence rather than the peace and justice that were promised. This paradox underscores the complexity of human ambition and the fraught nature of societal change. The question arises: can true justice ever be attained through violent upheaval, or is such a pursuit inherently flawed?"
