Why didn't Wukong resurrect Sun Wufan (Wukong's grandfather) with the Dragon Ball?

In the Red Ribbon Army (also known as the Red Silk Army and the Black Silk Army), because the last dragon ball radar could not be found, Wukong and others went to see the divination mother-in-law. In that episode, Wukong saw his grandfather who could come and die one day because of his mother-in-law!

Wukong, who needed the Dragon Ball to resurrect his father at that time, was embarrassed to resurrect his father with the Dragon Ball after knowing that Wukong's grandfather had also died. At this time, Grandpa Gohan said that he had a good life in the underworld and didn't want to be resurrected!

Therefore, Wukong never thought of reviving Grandpa Gohan with the Dragon Ball.
