If you use Bitcoin-QT (or any wallet client, including some web ones, that allow you to import private keys using just the priate key) you should be able to import the wallet, send money out, and then remove that address from your wallet once again.
It'd be up to you to be sure that you deleted any trace within your memory or hard drive of that private key. But if you could do that with certainty you should be able to 'import' your paper wallet momentarily, send BTC out to another of your addresses (or to someone who is expecting payment) and then delete it again. All without having to update all your backups.
This is
HORRIBLE advice. Advice such as this almost guarantees that someone will permanently lose bitcoins. Please refrain from giving advice on how to secure your wealth when you ahve no idea what you are talking about. Some uneducated newbie might actually believe you!
Hmm I believe you're right given your num of posts... But could you explain your reasoning (rather than just 'get mad')?
