One of the earliest examples of Saiyan pride in the series is Gokū's match with Piccolo Junior, in which the young Saiyan gambled the entire free world on beating Piccolo without outside interference.
The pride of the Saiyan race is what pushes the individual to revel in a battle and enjoy the fight even Saiyans such as Son Gokū, who weren't raised by the Saiyans during their formative years, show this tendency, proving it is an innate characteristic and not a learned one.
The Saiyan's Pride (サイヤ人の誇り, Saiya-jin no Hokori), is an ideology of the Saiyans common to the 7th Universe, as well as part of their mentality from birth. Vegeta to Trunks in ' Son Gokū's Mysterious Behavior' Shut up, Trunks!! I guess you don't have a Saiyan's pride! I'm sure he'd rather choose death than win that way! He's no longer fighting just to save the Earth.
