Is this a cold decision?

Only you know the specifics Cainite with each individual you are considering cutting off.
I have had to cut a few off but like EP mentioned there were chances with boundaries clearly layed out, each case turned out different and only one is truly cut off now because others learned to work within boundaries of what was kind/healthy.

Even the one who is still n/c if they did come and truly offer their half of a healthy relationship I would try again. Only you know what you can handle, what will allow your heart to heal.

I would say like EP having been cut off it truly was worse than death. Like mourning the death daily of someone who still lives and you deeply love. I would offer that to others only when necessary.

Thankfully it didn’t last more than a year in my case before they came back and the person had cut everyone off I wasn’t being punished just collateral damage. Still the pain was immense.
Even now the friendship mended there is still baggage I have to carry/heal from having one of my closest loved ones disappear by their own free will.

Just be compassionate to yourself and if possible consider each individual separately.
You are a thoughtful intelligent person. I know you can decide who is salvageable or who may not be. Life is hard. I wish you many loving and co-nurturing relationship to get you through.
Sorry you are even having to contemplate this. You must be in a tough spot.
