Bad Endings in Vidya

What are some good examples of bad endings in vidya? A good "bad ending" should make the player feel bad for not trying to get the best ending, in my opinion.

The mutant choice in Fallout 1.

The best good/bad ending example I've ever seen in a game was from Hunted: The Demon's Forge. If you actually listen to what the NPCs and lore text say, it's really easy to stay on the good ending track, even on the first try. But it's also really easy to get the bad ending, if you decide to take the easy route through even once. It was certainly a satisfying conclusion, especially getting the good ending on the first co-op playthrough.

The best bad ending I've seen period, including visual novels, is Sparks Liner High.

If you fuck up too badly too badly during the campaign, most of the endings have you sent to the gulags and shot.

Corpse Party has a bunch of bad endings.
