@moonlight00
why would he kill them, they have no reason to stop him anymore, and he have no reason to kill people obeying order
in their PoV, "he's stronger than the current boss, let him pass and he'll be the next boss"

that sure make it one of the most powerfull SCP and XK event protection, but I'm not sure that some "non-entity trigger" scp would be killed by it (don't remember the number, but the scp which have the milky way in a room, and destroy one of the star inside would destroy one outside)
@grandygon
Definetly Euclid for now
could almost be considered XK event trigger, but very unlikely since he don't want to destroy humanity (at least for now)
