Hackers are a blessing. Imagine what the world of internet security would look like if there were no hackers to fight. Even the most hardcore security paranoids would have trouble staying interested when there was no apparent need for it. Hackers are a continual reminder that we still suck at programming, and that we have to get better. Think about the consequences of not trying to get better. If every government system still had the sort of security we used 20 years, and some other country wanted to disrupt things, all they'd have to do is a spend a little bit of money training up some warrior-hackers of their own, and make a huge mess of things. So I'm glad that there are hackers around.
