Bjarnson - It's possible this creature does not hold the same values as you, or even understand your opposition to its action. Many elementals I have met have no concept of mortality or Spirits as they have none themselves. Does a mountain care if a rock is worn away? Will the stone mourn a loose pebble? And yet, a tribe considers every member as unique and important, even down to the weakest child. Its possible these creatures have as much attachment to eachother as you do to strands in your cloak - they may not understand the value you place in your own Spirit or that of your kin. Or, perhaps, it cannot act as other than it did: can your sword be anything other than a sword without your intervention? Perhaps this Judge cannot act except in judgement. If you learned anything from the Hearthmistress, it's to understand non-mortals do not think or act or mortals.
Suffice it to say, I would caution against hostility as your first recourse. Defense is often warranted, but unchecked aggression tends toward more imbalance than less.
