In situations like this, it is usually best to target both the significant individuals and the group as a whole in their own rituals. I don’t remember how the book suggests wording your requests, but something like “[Name] was unable to harm me,” and, “[Group] was unable to harm me” would be a good approach.
You do not need to repeat this. Do the binding and let that work. If you are trying to scheme and manipulate this person or group, then I would do other rituals with other demons after this. If you can tell your binding is having an effect, but it seems that there is still resistance or aggression against you, then subsequent rituals to confuse, weaken, persuade, whatever you need to happen, do those rituals and let them influence the situation as it unfolds.
Be wary of giving in to paranoia or letting your fears get the best of you. If you have an enemy who is attacking you, and then they stop attacking you, there is no need for further magick. It is done. Accept that the demons have brought you peace and move on with your life.
I do not know your situation, but if there is someone suing you, then this sort of patient and comprehensive approach can work well. I have seen magick render people unconscious, instantly. Sleeping, but immediately taken out of the situation. I have seen magick cause people to behave in ways that they never, not in a million years, ever fuckin ever would have behaved otherwise. This is not just a way of organizing your thinking and enabling you to be a dark machiavellian manipulator.
If you want revenge, there are demons who are very, very willing to assist you with this, to whatever extent it is that you want. Something I always ask myself though, before putting myself into the situation to have many curses and manipulation magick to perform, is would I rather be doing money magick? Would I rather be doing artistic inspiration magick? Do I want to spend my time dwelling in hatred and fear? Would I rather be rid of enemies and instead spend my time on friends? I am not judging you either way. I have certainly cast my fair share of revenge spells and curses for the fuckin fun of it, and chosen to spend my time amongst those who were actively hostile towards me. How you live your life and the decisions that you make is up to you.
Not to imply that you should be a doormat, though. If someone tries to take from me or mine, and negotiation and conflict resolution do not work, and it is not feasible for me to just remove myself from the situation, all bets are off. I dislike war. It is expensive, time-consuming, isolating, and painful, and all too often it bleeds out onto those you care about. But not everyone shares this belief.
I most definitely understand the need to toughen up after a life under oppression, but where you put your attention is what you cultivate. Do you want to cultivate something which you want to destroy, or do you want to cultivate something which you want to solidify and make stronger? There is no right or wrong here, no good or evil, only choice and the natural consequences of the actions that you do and do not take.
It has been said that the wise warrior spends more time in the calm of meditation, than in the fury of battle. Even the wisest of fighters may forget that arms are not always required. I like to know that my friends have weapons and are capable with them, but there is nothing more miserable than betrayal. Wielding them in training and play is so much fun, but there is no joy when they are needed.
Perhaps there is no joy for you anyways, and you are surrounded by enemies. In that case, you should be aware that the demons come readily when they are called and execute what is asked of them efficiently, without hesitation, and without play.
