A former prosecutor turned president has been sentenced to spend the rest of his life behind bars after his risky political maneuvers finally caught up with him.
Yoon Suk Yeol, 65, received a life sentence Thursday from Seoul Central District Court for orchestrating an insurrection, marking a dramatic conclusion to his meteoric rise and spectacular collapse from South Korea’s highest office.
The former leader’s reckless decision to impose martial law ultimately sealed his fate, according to those who worked alongside him during his career in law enforcement and politics.
A telling glimpse into Yoon’s mindset emerged from former judge Han Dong-soo, who recalled a 2020 dinner conversation where the then-powerful prosecutor made a startling admission.
“If I had gone to the military academy, I would have staged a coup,” Han quoted Yoon as saying during the evening gathering with flowing alcohol.
The court determined Thursday that Yoon violated constitutional principles by implementing martial law, sending military forces to invade parliament and attempt to arrest his political rivals.
Looking noticeably thinner than when he was arrested a year ago, Yoon appeared pale and shaken as he listened to the verdict while dressed in a dark suit. His legal team expressed opposition to the ruling and indicated they would consider filing an appeal.
Yoon has consistently maintained his innocence, claiming his martial law declaration served as a necessary alert that democratic principles and liberty faced danger from “anti-state” elements attempting to seize control of South Korea.
His path to the presidency began through his work as a prosecutor investigating sitting presidents, which made him widely recognized across the nation.
“Yoon Suk Yeol was the most powerful prosecutor-general ever,” Han observed, having overseen internal affairs at the prosecutor’s office during Yoon’s tenure.
“He used the office to carry out his plan to become president and in doing so, his actions were daring.”
By 2022, following his leadership of a corruption probe involving the justice minister, conservative voters who had grown frustrated with then-President Moon Jae-in’s liberal agenda embraced Yoon as their presidential nominee.
However, his time in office brought constant conflicts with opposition forces, which former prosecution colleague Lee Sung-yoon said revealed the reckless tendencies that had always characterized Yoon’s approach.
When Yoon declared martial law in December 2024, his political standing had severely deteriorated due to controversies surrounding his wife, Kim Keon Hee, who faced accusations of improperly receiving gifts, though charges weren’t filed initially.
Following Yoon’s removal from office, a special prosecutor’s investigation led to Kim’s bribery conviction in January, resulting in her current 20-month prison sentence.
The year leading up to Yoon’s martial law announcement was marked by continuous opposition battles that prevented his policy initiatives and legislative priorities from moving forward.
Despite domestic struggles, Yoon achieved notable success in international relations.
His efforts to end a longstanding diplomatic dispute with Japan and establish trilateral security partnership with Japan and the United States stand out as among his limited policy victories.
Yoon’s ability to connect personally with world leaders was memorably demonstrated at a 2023 White House gathering, where he surprised then-President Joe Biden and thrilled the audience by performing the 1970s classic “American Pie.”
Coming from a wealthy background, Yoon performed well academically and gained admission to prestigious Seoul National University law school. However, his love of social activities caused him to fail the bar examination multiple times before finally succeeding on his ninth attempt at 30 years old.
During his prosecution career, colleagues knew him for his relaxed demeanor, but associates noted increased ambition following his marriage to Kim, an accomplished art curator.
His presidency began controversially when he relocated the presidential office away from the historic Blue House complex, raising speculation about whether feng shui beliefs regarding the location’s supposed curse influenced the decision.
Yoon rejected claims that he and his wife had any connection to a shaman.
Critics accused him of protecting his “yes men” when he declined to dismiss senior officials after a Halloween crowd disaster claimed 159 lives.
Among those he protected was Safety Minister Lee Sang-min, a fellow graduate of Yoon’s high school, who later received a seven-year sentence for his involvement in the martial law declaration.
Another high school classmate, Defense Minister Kim Yong-hyun, previously served as presidential security chief and now faces insurrection charges for allegedly being the primary advisor who encouraged Yoon to impose martial law. Kim has denied any wrongdoing.
Political science professor Shin Yul from Myongji University believes Yoon’s downfall resulted from following bad advice, suggesting the former president likely “still thinks he did the right thing” regarding his martial law decision.
