On the subject of Mercana and the appropriate times to use it, in a previous lore thread you've said the following.

"...If a threat, such as a monster, is about and the only way to make sure it's stopped is to heal someone who can defeat it, that is another valid use. If you are pursuing a greater threat towards others, such as monsters (but not mortals), then it can be used without much worry..."

Aren't there scenarios where these tenants can potentially conflict? For instance, a serial killer or murderous assailant is a greater threat towards others, and also a mortal. Potentially one that could be stopped by healing someone capable of defeating them. Is it legal to use healing Mercana in just about any circumstance where the consequence of not using healing Mercana could reasonably lead to someone's death? Or is there a threshold of danger that must be surpassed? If so, where would such a threshold lie?
