Goku is pure of heart, possessing no negative feelings or thoughts. He is highly loyal to his friends and family and is extremely protective of them as a result. He loves them very much that he is willing to sacrifice himself to save others as he did against Raditz and Cell.
 
He strongly believes in repaying debts, as he gave the then-evil Vegeta a Senzu Bean for technically saving Gohan and Krillin from the Ginyu Force. He is a man of his word, committed to keeping his promise no matter what; 2 prime examples being the resurrection of Bora and giving the Omni-King a friend even more fun than himself. He has a very practical and carefree view of life, and his goals are very simple; he only seeks new adventures and challenges like testing his limits as a warrior.
 
He has no interest in luxury or high-ranking positions, as he rejected Kami's offer to become Guardian of Earth and, likewise, Whis' offer to become the next Universe 7th's God of Destruction, though the latter was mainly due to his morality making him unsuitable for it. At the same time, he shows such unwavering will and tenacity to succeed, always determined to never give up against any adversity
