Well, most of the time an attacker's objective is to take down your server. If you take it down yourself, you're giving him a premature victory. (imo)

Edit:

Adding to the above, if the attacker has got a strong method of attacking your server, shutting down the server (and saving user profiles, preventing data loss) would be a better choice. The server would go down eventually anyway.
