The game sees it as your fault if a "static" NPC takes damage. This means that NPCs that you poison with the enviroment, or lead enemies into attacking, will cause them to aggro. It's only one of the many reasons to never fight near NPCs you don't want dead.

However, Siegmeyer's final encounter and Solaire during summoning are examples of characters this doesn't apply to. This is because they will take damage, and thus would automatically aggro you within seconds. However, both would aggro you outside of these situations, as they are no longer supposed to take damage.
