For an end-user license, sure. But even so the license restrictions only apply to the _recipients_. So if I'm the NSA and use GPL code, and only distribute it to NSA colleagues, I only have to provide my NSA colleagues with the license and code. (IANAL, but seems pretty clear to me on this)
You're right that if it's just a copyright on the source code, then it's probably a restriction on redistribution, which means you couldn't _use_ that code for evil and then share it with others. But using it for evil for yourself: totally fine.
