I stored my raspberries wrong and may have eaten spoiled berries?

If they were getting soft, they were close to spoiling but havn't quite gottent there. I like them on my cereal so when they get soft, the texture isn't as nice but they still taste fine. But when raspberries go bad, you can't mistake it, because they very quickly get a greenish or whitish fuzzy mold on them. And believe me, just the tiniest speck of that mold on your berry throws the taste WAY off. It's a very musty and bitter taste. You're right though, the trick to storing them is not let them be closed up in an overly moist container or bag.
