Tonytoni, I'll assume the family whom you want protect includes your offspring. I won't assume which parent you are, because it doesn't matter.
How your SIL and BIL behave is up to them; you have no control over that. Your home, on the other hand, is not under their control, and if you accept your SIL "blowing off" your "he is not welcome," you will have ceded control of your home to her - and him.
The most relevant reason to enforce your boundaries is distance. IF he enters a "murderous rage," you want you and yours to be non-entities to him, nowhere near his thoughts. No recent inadvertent slight from your spouse or youngsters, nothing that he could take "wrong." It sounds as if you could use the wrong mustard and he might fly off the handle.
"Violent people are not welcome here. Period." Threats of arson and death are not to be taken lightly, and I doubt that you have evidence one way or the other of any past acts of violence. You don't know, and BIL swearing on a stack of bibles that he's never hurt anyone or burned down a building is not evidence. The "whole family" really can not "know" any more than you do. So far, all he knows is that you're willing to accept the threats.
Make it clear that you are not willing. Keep him away from your home, your spouse and your children. They could disagree with him that it feels too warm outside today and he might feel devalued or feel his teeny-weeny ego threatened.
If your spouse becomes petulant about not having sis in your home, remind spouse that #1 is spouse and offspring, and that you will not tolerate, monitor, or give "one last chance" to BIL. BIL has violated trust, and it's O.V.E.R.
Spouse might be upset, but is probably too close to sis to see BIL objectively. Sis thinks it's "okay," so it probably will be "okay." No. This one is on you, because you are the one who can see them all clearly.
Of course this will isolate your SIL even further, but your first priority is your family, safe in their own home.
