Yes, they can spoil. I have had rancid nuts right from the store that were inedible. That includes the ones packed in sealed jars or cans. But worst, my mother had some walnuts she kept in a bowl. They looked fine but they must have been there a long time because when we cracked them open just dust was inside. Then there are the packaged nuts they sell for baking. Half the time these are turning rancid if not already rancid. You've got to find a store where the turnover is high and there is less chance of them keeping old stock on the shelves and selling it. Nuts can definitely spoil. Try to get them as fresh as you can.
