What was one important decision Thomas Paine made?

The most famous decision Thomas Paine made was his decision to write Common Sense. This book brought him fame in the American colonies when he claimed that the Americans were destined to win the Revolutionary War due to the righteousness of their cause. His work encouraged borderline patriots when the outcome of the war looked bleak for the revolutionaries. Thomas Paine's plain words and easy-to-follow arguments were popular throughout the colonies.  
Paine later went to France, where he was received as a champion of democracy. At first Paine and other liberal Americans cheered the overthrowing of the French crown and the execution of the royal family; this was considered a new era in government. However, when the Reign of Terror began and the executions did not stop, many Americans became critical. Paine was arrested as an enemy of the state and it took efforts on the US government's behalf to have him returned home and saved from the guillotine. Thomas Paine is best remembered for his work Common Sense; because of this, he achieved fame in his life and in history.
