Apologies to bump in, and this what I am going to say next should be good advice for myself as well..
Don't just assume that when one moves out of life they won't come back biting the butt.
We need to be ruthless against our enemies, that means even if they might be a potential threat they should be bound.
Some people seem fine but end up keeping a grudge or whatever against you behind your back. (There are a lot of backstabbers, gossipers and what not in this world too)
While we may be compassionate towards others, our brothers and sisters especially, we should remember that we are at war. And that means that who ever is even a potential threat should not be ignored, but rather either kept an eye or on or taken care of (and I mean bound in this case).
As for Johnson, may I ask, the binding in the witchcraft section, do you follow that procedure or did you change something about that?
