Goro is merely serving his realm....but he's got his own feelings as well.
Here's how it goes down. Goro is 1,000 years old and he's the prince of the Shokan! Since King Gorbak (according to the MK1 manual, that's the name of his father) didn't have the proper time to raise his child, he had his servant Kintaro raise him for him (Kintaro spawned Goro, says his bio). Nevertheless, Goro became a strong leader and a strong fighter thanks to Kintaro's teachings.
When he was 500, he met Shang Tsung, and since the Outworld wanted to expand and make themselves more powerful, the Shokan would become more powerful too, he invited Goro to compete in the tournament to win for Outworld. Goro decided yes. It was then that Goro entered the Mortal Kombat tournament and demolished every opponent. EVERY opponent. He eventually came face to face with the champion Kung Lao (the original). They fought, and Goro killed him in battle, and Shang Tsung took his soul.
FOr every generation, he continued to win fights for Outworld and tournaments. No one could oppose the new champion of Mortal Kombat. Every tournament he won would get Outworld closer to unbalancing the furies and control Earth as part of Outworld. Goro kept winning and winning....then the year 1992 came. By this time, Goro was 1000 years old.
To Shang Tsung's surprise, the Earth warriors began to win. Goro decided to put a stop to this, and fought the Earth warrior Liu Kang. Liu Kang and Goro fought! In the end, Goro was beaten by Liu Kang. When the tournament ended, his body couldn't be found, so it was assumed he was dead. In actuality, Goro had run away into the Outworld, ashamed to show his face to his Shokan people and to Outworld since he had lost the tournament and Earth was out of their grasp.
He remained lost for five more years. No one knew where he was.
Finally, it came to his attention that Liu Kang was within the Outworld. At this time, Shinnok and the Netherealm were expanding. Goro decided to finally show his face once more to take his revenge on Liu Kang for defeating him. But while witnessing Shinnok's power and what was truly at stake, he realized the grudge he had held and the trouble he helped Outworld cause was far more important to undo rather than a grudge he had helped along the years. Finally at peace with himself and accepting his losses and deciding to focus on increasing peace, he returned to the Shokan people, much to their happiness as he was thought long-dead. When Shinnok's malice ended, Kitana went to Goro and asked him to help her increase the peace by signing a treaty between the Shokan and their rival tribe, the Centaurians. Goro agreed, but was attacked by Kung Lao. The attack was merely revenge for Goro murdering his ancestor years ago. Now that they're even, Goro and Kung Lao decide to make their own peace.
Now that things are cleared, Kitana and Edenia ask for Goro and the Shokan's help to demolish Shao Kahn and Outworld once and for all. Goro agrees, as he has caused enough trouble, and they join forces to end the malice. The war seems unwinnable, but Goro and Kitana push on. All of a sudden after a battle is finished, Goro (tired from all the fighting) is attacked by the warrior Noob Saibot - sent by Shao Kahn - and mortally wounded. It was too bad, and he ended up dying from his wounds.
His body was taken back to the Shokan, and they ceremonially dipped his body into lava.
That's all his story up there ^^^^^ will he be back? Who knows?
