Thinking back to when Frieza destroyed Planet Vegeta and wiped out nearly all of the Saiyan race, I think he did the entire universe a favor. Could you imagine if they started gaining more strength and one by one started achieving Super Saiyan status? They would have not only overthrew Frieza's army but effectively took over the universe. Not to mention, Goku would have grew up on Planet Vegeta and would have never become a "good guy". But this is just with the Saiyans. Where would Earth be without Goku? I think King Piccolo would have essentially taken over the planet.
It seems the domino effect that Frieza causes by destroying Planet Vegeta and nearly all of the Saiyans ended up safeguarding the universe.
If we throw Beerus into the mix though, then we would know that he was told to do this by Beerus himself. Frieza had been essentially using the Saiyans at the time and gaining more power over planets through them so maybe Beerus wanted to stop both of them from having too much power. Who knows. I could be overthinking this or forgetting details.
Either way, I think Frieza did good by doing this. Change my mind.
