[Venom] Why does the arrival of the symbiotes on Earth create any conflict really, when we all know for certain that the symbiotes can survive by eating animal flesh instead of humans'?

There's that one scene with Brock, unknowingly carrying the symbiote, really needing to feed it in order to survive. But then for some reason instead of going after the humans (which seems to be the purpose of the symbiotes in the first place), Brock/Venom makes their way to the lobster tank in the restaurant, and feasts on live lobster before being dragged out of there with the other guy pretending that he's his client. Okay.

But... whatever, why did the symbiotes even pose a threat to humankind anyway? Did they come to Earth in order to eat, or are they power-hungry? What is the overall nature of their visit? I'd thought it was just to feed, but maybe they also wanted to control the planet.... I'd just thought to myself when I saw the movie, oh well that'd be cool. And people eat meat here on Earth anyway, so why would it matter if another carnivorous species - especially one that gave its human host superpowers that are out of this world - came to Earth? Since people could just feed them cows, or live fish, or maybe even live insects, and then probably not even have to eat anymore on their own. 

Am I missing something here, or what?

They possess humans and slowly consume them while doing so.

It's easy to forget that, with Venom being such an accommodating symbiote, but unless Riot found the one little girl totally down with alien conquest, the symbiotes don't *have* to consider their hosts human desires and goals at all. They can just take over and make them do whatever they like. We even see Venom do it a few times. And we can perhaps assume most symbiotes lean more towards Riot then Venom.

They might not eat us all, but compared to us all being conscious but helpless as alien parasites use our bodies as puppets while slowly rotting our internal organs, that might not be a kindness.
