In the Bible Jesus shares on what to do when someone attacks you - you need to BIND the strongman first.
Then let God do what He needs to do. Binding is to stop them from doing further harm - in the context, its demons, but this is also why security or police arrest /handcuff or restrain offenders then detain them, they don't just shoot people! or strangle them! Then they are trialed and found guilty or not. That's the way it works. Otherwise people are no better than murderers that take vengeance in their own hands.
