What is the worst thing william mckinley did?
<|assistant|>
William McKinley is primarily remembered for his leadership in helping the United States join the ranks of global powers following the Spanish-American War. As an unanticipated side-effect, his term as president saw a large expansion of the powers of the presidency, often leading to accusations of tyrannical behavior by critics. His most controversial decision, however, was his agreement to join the Filipino revolt against Spanish control--though ultimately seen as heroic--during his tenure, McKinley's critics often cite it as evidence of his imperialism. As a result, his legacy is often seen as tainted due to the large human cost associated with this conflict, ultimately contributing to his assassination in 1901.
