How many times has it happened with you that you left eggs to boil and forget about it? We are sure not once but this has happened a couple of times with all of us. But that does not change anything, right? You go ahead and eat them.
Let's give you a shocker! You should not eat overcooked eggs. Here is why.

When you boil eggs, hydrogen sulphide - a toxic gas is released in the whites of the egg. This happens especially when you overboil the eggs. If you have noticed, overcooked eggs have a green coating on their yolk, which is a signal that you should not eat them.

Why it happens?
The hydrogen sulphide originates in the whites of the eggs and the protein in the white contains sulphur that combines with the hydrogen to form a deadly gas. This hydrogen sulphide heads towards the inside of the eggs. As the outer shell of the egg gets hotter, the gas is forced towards the yolk.

The egg yolk contains iron and when this iron meets the hydrogen sulphide gas, it combines with it to form iron sulphide, which gives the yolk the green outer lining. So, the more you boil the egg, the more sulphide is made and the thicker is the green coating.

That is why the recipes that involve hard-boiled eggs recommend putting the eggs under water as soon as they are cooked to cool them off quickly and keep the residual heat from overcooking them.

Though no casualties have yet been reported as a result of hard boiled eggs consumption, but it's better not to eat them as the gases produced while overcooking eggs are toxic and can suffocate and poison people.
