I cut an onion and it had white mush under the skin. But when I ripped alot of the external skin off, it was hard and firm and seemed normal. bad?
Yes, now that you mention it. It smelled a little off.
Then it's definitely possible that the onion was going bad. It's always important to inspect produce before using it in a recipe, especially if it's been sitting in your pantry or fridge for a while.
