Maybe Saiyans dont say that lol

Obviously, because Saiyans also have a tyrant, King Vegeta. Saiyan are born warrior and compassion aren’t being taught as it’s treated as a weakness amongst them, so they’re basically a race of ruthless fighter, and King Vegeta is on the top of that. He went and conquer the stars, and only stopped because of Frieza, the bigger tyrant.

The only good saiyan is Goku, all due to the head trauma and also raised by Gohan. Vegeta only being good because of the bigger tyrant, Bulma.
