It could be something like "you killed, and so you die" sort of thing, in which case Ban's immortality would be at play similarly to how Escanor's pride made him immune to  Estarossa's Love

But I'm guessing that Pacifism may not be activated simply by killing, mostly because Estarossa was going to kill Meliodas while Gray Lord was there.
