What are the important factor of the case the unabomber?

The Unabomber case, involving Ted Kaczynski, was marked by several key factors: Kaczynski's radical anti-technology ideology, which he articulated in his manifesto "Industrial Society and Its Future"; his methodical approach to his crimes, targeting individuals associated with modern technology and industrial society; and the lengthy FBI investigation that ultimately led to his capture in 1996, largely due to the recognition of his writing style by his brother. The case raised significant discussions about mental health, domestic terrorism, and the implications of technology on society.
