um okkkk Earthia is scary

so I'm looking back to the SonicX english dub episode 74 
the flashback episode with Lucas and Earthia 
and this totally flew over my head the last time I watched this (I haven't watched SonicX in the longest time) 
"Hundreds of beasts (the male seedrian seedrex/thorndrians) are still resisting!" 

Earthia: "then we have no choice but to DESTROY them" 

um 
Earthia killed hundreds to thousands of seedrex/thorndrian 

...............

I don't know what to do now that I know this information
