I'm a Green Lantern. I fear nothing. Fear is the enemy of will. Will is what makes you take action. Fear is what stops you and makes you weak. Makes your constructs feeble. You must ignore your fear. When you're afraid, you can't act. When you can't act, you can't defend. If you can't defend, you die.

Thaal Sinestro was the Green Lantern of Sector 1417 and the mentor of new member Hal Jordan.
History
Origin
When Sinestro earned his ring, he was a law enforcer on the planet Korugar. But he grew disappointed by the government and tried to lead the inhabitants against their leaders. Despite the opposition of his fellow enforcers, Sinestro was willing to sacrifice himself. Right before being executed, a Green Lantern ring landed on his hand and took him to Oa, the planet of the Green Lanterns. For his entire life, Sinestro thought the Green Lantern Corps was a legend, for they never helped end the civil war that has been affecting Korugar for years. On Oa, Sinestro met Abin Sur, who helped him see that his role as a Green Lantern is to seek justice, not vengeance.[1]
Years later, Sinestro claimed that he helped unite the people of Korugar, teaching them to be without fear.[2]
Green Lantern
When Abin Sur was on his way to assist fellow Green Lantern Fentara, he was contacted by Sinestro who informed him that Fentara had been killed and warned him to be careful. Devastated by Sur's death he address the Guardians of the Universe. When Hal Jordan arrives on Oa as Abin Sur's replacement, Sinestro is not pleased that he was a human stating that it disappointed him that Hal was wearing Sur's ring. This caused Hal to see himself unfit for the training and return to Earth. Sinestro and a few other members of the Corps confronted Parallax but could not stop him.
All the Green Lanterns who went on the mission were killed easily by Parallax except for Sinestro who refused to fight, seeing what happened to his fellow Corps members. Sinestro suggested the Guardians should forge a Yellow Lantern Ring containing energy from the essence of Fear and use it to defeat Parallax because he thought you can only fight fear with fear. Hal arrives and tells him not to use a Yellow Lantern Ring because once corrupted by fear you cannot turn back, he requests that Sinestro and the Guardian's help him save the Earth from Parallax. His request, however, was denied so Hal had to defend his world on his own.
After leading Parallax towards the sun, Hal was about to be pulled into its core by gravity beacuse he was exhausted and it was too strong for him to fight, when he was saved by Sinestro, Kilowog, and Tomar-Re. Sinestro commended Hal's achievements and told the Corps that the threat had been destroyed. After witnessing Fear's power, Sinestro retrieved the Yellow Lantern Ring that had been created earlier, he slipped his green power ring off his finger, and replaced it with the yellow ring, becoming the first Yellow Lantern.
