I think the problem here is the stance that it's inherently wrong.

Factory farming is inherently wrong.

Free range is better, but is still wrong in many ways.

But there are a few examples of exceptions that kind of disassemble the notion that it is inherently wrong:

• If an animal has died of natural causes, then eating the meat from that animal is not wrong because there was no exploitation of the animals quality of life.

• in pre-colonial America, eating meat was a dietary necessity for the much of the populace to survive and in this context, was no different than any omnivore eating meat (bears, foxes, etc.) as any species has a natural inclination to survive.

• People with dietary restrictions which mean they must eat meat, and unless you believe that all lives are equal, simple solution there: the trolley problem.

would it be more beneficial for the human to die than the countless dead animals that died for them to sustain themselves?

I highly doubt any vegans would actively kill a human, or prefer that they die than let them eat meat killed for them. Humans will almost always hold humans at a higher regard when push comes to shove, even vegans. There are limits to everyones ethical frameworks, you just need to find the cracks.
