Eating old eggs won't poison you or cause death however the old eggs can cause you to have a stomach ache.
Bad eggs that should be thrown out will give a bad rotten egg odor that will be noticeable and make you gag.
So as long as the eggs don't smell bad and are just a little past their expiration date but have been refrigerated they should be safe and fine to eat.
However if you're ever unsure whether the eggs are good or bad it's best to just throw them out and not risk getting sick from eating the bad eggs.
