A moral dillema - from StarGate: Atlantis of all things

[Orko]

So in StarGate:Atlantis, there is an alien race called the wraith, who consume humans(and only humans). They can't survive on anything else.
The show, subscribing to the regular black-and-white morality of crappy tv shows, present the wraith as extremely evil and cruel. But all they do is trying to survive the only way they possibly can. They treat humans like cattle, which is not different than the way humans treat their, well... cattle.
So what do you think?

[Lancy]

The wraith simply need to eat humans. They try their best to make this as easy as possible for the humans, sleeping for hundreds of years before going on a feeding frenzy. In between they allow the humans their civlisations and daily life, provided they remain technologically inferior. Indeed there are instances were we see them compromise with the humans to make things easier for them. The episode were we see a planet which sends its criminals to some island, which is where the wraith go to feed. The rest of the law-biding population is left free to not be eaten. Would an evil race of beings really be so accomodating?

[Helm]

We could come to an arrangement with them where we provide them with genetically modified brainless human clones grown in vats. Everyones happy.

[Ulyaoth]

I'm sure they could eat something else.

Besides, they're evil to humans, for your enemy is evil. That's all there is to good and evil, you good, enemy evil.

[Lancy]

I'm sure they could eat something else.

They really can't. They are an odd race of beings.

[Helm]

What did they used to eat before?

[Ulyaoth]

If they were so advanced they should be able to genetically engineer themselves to eat humans, or at least modify a group of humans into a pure cattle population, stupid and nonsentient.

What did they used to eat before?

And that's the other point, they developed as a mutation of humans anyway didn't they? Or whatever it was, they developed after humans had come to them, meaning they turned to how they are.

They are not all that advanced. Also, most of their technology is borrowed from previous civilizations. They are also kinda stupid.
Besides, why would they want to do that?
And back to the original question:
are they really evil as the show presents them to be? what are they exacly, morallistically?

What do I think? I think SG: Atlantis has bad acting, bad writing, and is really boring.

Yup. Stargate is crap. Battle Star Galactica is the only half decent one of those series on sci fi and it's not good enough for me to go out of my way to watch it, I just won't turn it off.

It's like if we could only eat pandas and nothing else, we wouldn't go to China and attempt to harvest them. Though if pandas were farmed for food that would bring them back from the brink of extinction quite nicely.

Cows aren't sentient.
They can try convincing themselves that humans are not sentient, but it's fairly hard considering they speak english
Also, humans offered them a retrovirus that would turn them back into humans and they refused, it would shorten their lives, but would absolve the moral dilemma.
They're mutated from humans, which somehow explains why they can only consume human beings, so they have no choice, however before puberty they can eat normal food.
Stargate is awesome(Atlantis was awesome because of McKay, mainly ). Battlestar is awesome. Star Wars is awful.
But mainly, they're evil because they're bloody space vampires! And speak in a creepy voice.

[Exarch]

aren't the wraiths more like parasites though?
