There are scads of examples of attempted deicide in D&D lore.

Now mind you, it does depend on the methodology. By and large, gods consider it extremely dirty to gun for the faithful of a power, even if they would secretly like to do it themselves - it's the kind of behavior that immediately leaps to a slippery slope. Varakhuts also hate that one. The varakhuts also hate things like what Karsus pulled, where deicide is less the goal than a potential consequence of abrupt cosmic usurpation.

Ultimately, there is no guarantee that a varakhut won't show up to harass you, but history stands clear on this point: attempts have been made in the past, and will certainly be made in the future.
Put another way, there is a sort of accepted game to divinity, and the rules cover how you're supposed to go about trying to kill or usurp an existing deity and how you can rise to godhood in your own right if you don't want to try ripping it out of the metaphysically steaming body of the god you just destroyed. Stay within those rules and play the game 'right', and if you succeed in killing a god that's just your proper due for playing well. Get caught cheating or trying to act outside the rules, and that's when the various concerned forces of the planes start coming down on you.
