Is this a cold decision?

[Anodyne]

Have you ever done this? what are your thoughts?

I have, and it's rough.

A decision like this is never made simply or easily. I personally tried everything I could to reconcile beforehand - gave them many "chances" before taking the final action. They did not comprehend the kindness or leniency I gave. When I cut them out, it was wounding to them. I grieved for their pain.

But! If taking adequate care of one's own self is NOT considered, we will not have the health to continue in service to others.

The toxic ones would prevent us from healing and being healed. That seems to be a goal they have, whether conscious or unconscious.
