Why not? If "God" is such a sick fuck that he gets off on designing mutually antagonistic creatures and pitting his playthings against each other, isn't It really a malevolent force anyway, and therefore better described as a devil than a "god"?

Since I don't subscribe to intelligent design, I don't believe any hypothetical God even designed any creatures in the first place. God may have created the universe and the laws that govern it, but the creatures therein are a product of natural law; animals are the way they are because that's how evolution made them, not because God wanted to see living killing machines go at one another.

And no, I don't think that even designing the natural laws to work that was is evil, at least no more evil than a scientist allowing penicillin to eradicate the bacteria in a petri dish is evil.
