It is possible that downvoting a post results in deletion of of a question; the precise rules are however a bit tricky.
Before downvoting, is it necessary to check if a downvote would lead to (very likely, say assuming absence of further vote on an old thread) autodeletion in the (near, say a week) future? (Or, what would be the appropriate notion of 'near'?)
If so, in which way should one need to modify or reconsider a decision on downvoting based on this check?
