The famous Greek philosopher sentenced to death for corrupting the youth was Socrates. He was tried in 399 BCE in Athens for impiety and corrupting the morals of the youth through his philosophical teachings. Socrates employed a method of questioning that challenged conventional wisdom and encouraged critical thinking among his students. He was ultimately found guilty and chose to accept his sentence of death, famously drinking hemlock poison. His trial, philosophical ideas, and the manner of his death had a profound impact on Western philosophy and ethics, laying the groundwork for his students, including Plato.
