creatures, harm,

Whenever one creature harms another, this is less than ideal.

Two things that I can now think of as causes for harm between creatures: lack of understanding, and conflict of interest. These need consideration. I think them to not be sufficiently encompassing. What about intentional versus unintentional causation of harm?

Anyway, the definition of harm needs to be considered as well. Is to withhold vital information from someone who needs it to harm them? Perhaps. If you push them out of the way of oncoming traffic with such force that you injure them, is this harm. Perhaps not. So, how to define it?
