To the best of my knowledge, the only thing that can not "go bad" is Twinkies...leave one on a plastic table and come back in a few years, there will be a twinkie shaped hole in the table, and twinkie will be on the ground.
As for M&M's, the hard candy shell will (eventually) breakdown, releasing alcohol as a by-product, incidentally. As for the chocolate, the process of making the chocolate (depending on the *type* of chocloate) generally means it does *not* go bad...ever. I'm not saying you won't see mould on chocolate if you leave it unwrapped somewhere for a couple of weeks, but still...
However, "Old" chocolate, or chocolate that has been exposed to poor storage techniques (alternating warm/cool cycles) will eventually break apart, resulting in a whitish coating. The chocolate is still edible, but doesn't taset as good, and has a grainy texture.
The link below will take you to as site that describes the process of making chocolate from picking the seeds to the final stage.

Chocolate can go stale if left for months. Many's the soldier that learned the joys of decade-old chocolate (including M&Ms) from an MRE pouch.

It's harder for them to spoil exactly, like get rotten, they'd need constant exposure to moisture... They normally go stale or the chocolate and the sugars start to degrade and that'll taste bad. It's not too likely they'll poison you, tho.
Good luck!

Ive had stale peanut M&M's before . so yes.
Never eaten the plain and they tasted bad though, even when I could tell they were really old.

yes. the chocolate turns bad and it doesn't taste so good. there is milk in chocolate so the milk turns bad in the chocolate.
