Goku Only Truly Hates Two Type of Dragon Ball Fights 

Goku is a fighter. This is evident throughout his Dragon Ball career. 

He even becomes more excited about fighting strong opponents because he knows he will be stronger. 

There are two exceptions to this perception of Goku. As Dragon Ball continuity suggests, these are the only types of fights Goku hates. 

Goku was introduced in Dragon Ball chapter 1, by Akira Toriyama, and readers are shown from the beginning how much he enjoys fighting. 

While Goku was initially fighting dangerous wildlife to kill them and eat them 

the joy of fighting was evident from the beginning and only increased as the story progressed. 

Soon, Goku was taking on fascist regimes around the world and defeating the greatest villain of all time.
