This article explores the assassination of conservative activist Charlie Kirk, placing the event within the broader context of contemporary political extremism and digital culture. It analyses the personal trajectory of the alleged perpetrator, Tyler Robinson, highlighting his self-radicalisation through online subcultures, meme-driven communities, and possible incursions into the dark web. Far from being a traditional militant, Robinson emerges as a hybrid figure shaped by digital echo chambers, toxic irony, and the fusion of ideology with internet performativity. The case exemplifies how online environments can catalyse violent dispositions, transforming personal grievances into lethal political acts.
