All that a state does is convince people. States don't really exist. They're fictional constructs that sometimes convince a police officer to break into a murderer's home and kidnap him. And most of us agree that's a good thing. However sometimes they convince a police officer to break into a protestor's home and kidnap him. And some of us agree that's a bad thing. Other times they convince bomb makers to make bombs and convince aircraft mechanics to attach them to airplanes and convince pilots to fly over hospitals and press the release button. That's bad too - sadly not everyone agrees on that.
