King cobras can hurt you badly, sure. But they won't chase you or attack you. Quite the opposite as they want no business with humans (they will raise their hood and hiss if you're near by, to let you know they are here, yes...). I can tell you that in Thailand at least, there are certainly way more deaths and injuries due to stray dogs than from cobras or any other snake. I's rather get rid of these dogs than of king cobras.
