There are several ways to neutralize deviled eggs that are too salty. Some are:
If it is too salty, you can add water or potatoes or both.
Start over :( sorry, there is no real easy/good way to fix too much salt in deviled eggs.
try adding lime juice as it will neutralize the base
if there is to much salt in the deviled eggs the best and only way to repair it would be to add more yolks.
take the salt off
Marinate with honey.
add more water
If it is just in the filling of the eggs, then you can take the filling out and re-fill them with a less salty batch. If it is on the hard-boiled egg itself, try washing it off gently with cold water.
put ketchep on it to neutralize the salt drink somthing or add kechup

Eggs of this style didn't become known as a "deviled" egg until the 1700s. The term originated in England and it means a food that is highly seasoned, chopped, ground, or whole mixture that is served hot or cold. The term doesn't just apply to eggs. Deviled crab and other types of deviled foods are pretty common, too.
I think you should sink it in water, maybe shake it a bit.
