"Don't, Tien Shinhan. He's my brother."
Goku's heart jolted. He was truly afraid that Tien Shinhan would beat his brother to death.
Although he had only just met this brother, Raditz was still his kin, still his brother. Goku found himself willing to forgive everything Raditz had done and give him another chance.
But Tien Shinhan was different. As a rotating member of the Red Ribbon Army, Tien Shinhan knew that Raditz had killed a farmer and six Red Ribbon Army soldiers the moment he arrived on Earth. That arrogant, contemptuous expression clearly showed that he regarded no one on Earth as worthy of notice. Who knew how many people he had killed with his strength before this?
Tien Shinhan simply did not want to let Raditz go.
Even if he was Goku's brother.
Furthermore, Tien Shinhan believed that Goku had already spared Raditz once when he first arrived. Not only was Raditz ungrateful, he had deliberately stalled for time until he saw the moon and transformed, intending to use that transformation to kill them.
Tien Shinhan, whose sense of justice was overflowing, could not tolerate Raditz's actions. Raditz had to die.
With someone this evil, if they ever left Earth, Raditz might very well immediately begin exterminating humanity.
Evil had to be eradicated to protect Earth!
"Awooo... Roar!!!!!" The mindless Great Ape Raditz had been struck so many times by Tien Shinhan that his chest was covered in fist marks. The pain made him roar furiously, especially since he could not land a single attack on Tien Shinhan. Great Ape Raditz stamped and raged in place.
Tien Shinhan's pupils darted rapidly left, right, up, and down, perfectly evading Great Ape Raditz's nearly airtight barrage of wild swats.
'Bang!'
In a furious rage, Great Ape Raditz slapped his own chest.
