What is the grand betrayal of Jose Rizal?

The "grand betrayal" of José Rizal refers to his disillusionment with the Filipino elite and the Spanish colonial government, particularly after witnessing their betrayal of the revolutionary ideals he championed. Despite advocating for reform and peaceful means of achieving social justice, Rizal felt let down by the lack of genuine commitment from those in power and the betrayal of his vision by fellow Filipinos who prioritized personal gain over national progress. Ultimately, this disillusionment contributed to his decision to sacrifice his life for the cause of Philippine independence, marking him as a martyr for the nation.
