Dragon Ball: Why didn't Wukong resurrect his grandfather with a dragon ball?

I think in Dragon Ball Z, when Wukong saw Vegeta become a gorilla, he just said the word gorilla monster. Gorilla monster was told by Wukong when he was a child. When Vegeta told Wukong that Saiyan people could become gorillas at the full moon, Wukong realized that Sun Wufan's gorilla monster meant himself.

At this moment, Wukong realized that he trampled Sun Wufan to death by himself. Since Wukong already knew that he had trampled Sun Wufan to death, collecting seven dragon balls could realize his wish. Why didn't Wukong collect the dragon balls and resurrect his grandfather? In fact, in the original dragon ball story, it has already been explained.

When Wukong and Buma first met, Buma told Wukong that collecting seven dragon balls could realize his wish. Buma asked Wukong if he had any wishes to realize. Wukong said no. In this way, after Sun Wufan, Wukong resurrected Sun Wufan. Although he knew the ability of the Dragon Ball, he didn't know that he trampled Sun Wufan to death.

Presumably, when Sun Wufan died, he must have told Wukong about the past. Therefore, when Wukong learned about it, he didn't want to resurrect Sun Wufan with the Dragon Ball. Later, when Wukong and Buma were looking for the last dragon ball, because the last dragon ball could not be found on the dragon ball radar, Buma and others went to Master Roshi's sister-in-law.

However, Wukong had no money, but in order to let his mother-in-law help him find the Dragon Ball, Wukong promised to fight with several of her men. As long as Wukong wins, he will help Wukong with divination for free. However, in the last battle, Wukong fought with the masked man. Wukong Wukong's weaknesses were known by masked men, so Wukong was suppressed everywhere.

Finally, Wukong's tail was caught by masked men and he gave Wukong a good beating. Finally, Wukong's tail was directly broken. Goku, who showed no weakness, began to fight back. The masked man was no match and finally had to take off his mask. Wukong discovered that this was his grandfather. Wukong burst into tears when he saw his grandfather. At this time, Buma said that he would use the Dragon Ball to resurrect Sun Wufan.

When Wukong heard this, he also explained the ability of the Dragon Ball to Sun Wufan, but Sun Wufan finally refused. It can be seen that Wukong doesn't want to resurrect Sun Wufan, but neither does Sun Wufan. Sun Wufan didn't want to be resurrected, because Sun Wufan didn't go to hell or heaven after his death, but went to gossip about the old gentleman. Besides, the old gossip man is a beautiful woman, so Sun Wufan doesn't want to come back to life. All the above are personal opinions.
