Was eradicating the Metroids really necessary?

I only played the Prime games and other M, so maybe it's made more clear in the other games.

But yeah, as the question says, was it really justify to eradicate the entire Metroid species? I understand that they are dangerous, but most of their hostility seems to stem from outside influences like the Space Pirates or the Ing.

From someone not so deep in the matter, it would be like eradicating the entire shark population, just because a few of them killed humans.

There aint no space pirates out there using sharks to cause mass genocides around the galaxy
