What would I do to Achaia if I were in Niko's place?

Chances are that you already know who are the Achaia and who TF is Niko. Well if you don't, Achaia are an ultra advanced civilization based in a far off planet. Until so far they have been discovered in the Netflix series "Another Life" only and Niko is a firebrand woman who's the commander of the mission which was launched from earth once a strange alien ship came to earth and started growing a crazy looking artifact.

Without any further ado, I would head towards the Achaia planet after witnessing the destruction of "Zakir" civilization planet near Canis Majoris. I'd go FTL(Faster Than Light" and blast the bloody planet with full force of the particle bubble which forms around Salvare(the protagonist space ship).

But we also know that the Achaia got their artifacts already present on about 300 planets. Maybe they're already settled on some other planets as well and we destroy their origin planet, they'd come for earth.

But the problem is, they'll come for earth anyway. In that case Niko's decision to head back to earth sounds reasonable, maybe she'll be able to buy some time for the human civilization.

I thought this yesterday and I believe I need to document it somewhere. I got similar thoughts about other series like Altered Carbon, Lost in Space, Dare Devil, Punisher etc.
