Wait, why do we slaughter all these monsters?

In the cutscenes the characters will hold rousing jrpg style speeches about how we have to fight for what we believe in blabla. But how does that translate to going out and just utterly decimating the local wildlife? I could understand if they just fully embraced that they were cynical game hunters in it for profit. But they seem to maintain some kinda moral drive behind it, without it being super clear how theyre helping anyone or anything.

I know, I know. Its just an excuse to go out and do sick combos on monsters, but all the high horse stuff rings kinda hollow when we go out and savagely murder some random animal just minding its own business, chopping it up as it limps away to try and save its own life, drooling from its wounded face.

Kinda wish they just made it more straightforward, big monsters bad, kill and eat humans all the time, go end the threat. Thats why I prefer to fight the aggressive monsters that engage you on sight, a bit easier to justify.
