[WALL-E] Why is EVE's first instinct to shoot anything that moves?

We see that she immediately blasts WALL-E and the cockroach as soon as she noticed their presence. But if her directive is to find plant life, why would she risk shooting an animal which might lead her to plants? What would she be defending herself from?

She was never intended to find plant life. She was programmed to keep up the pantomime of looking for life, but it was taken for granted the earth was now liefless. The programming isn't made to be useful for finding plants, just for running around making it look like you're doing that.

Under her a*ctual* directive, any animals would be the last few starving desperate creatures on a lifeless world, and thus likely to attack any potential foodsource. Hence the immediate defensive attack- they're threats, and they can't lead you to any plantlife anyway.
