I still don't see end means with the troll thing every example here doesn't make sens. My advice to dev is make it like a bear, neither good or evil just a dangerous wild animal that needs to be treated with caution and respect.
This is a fantasy world with D&D-style creatures (pre-upcoming version). That means TROPES of some creatures being naturally evil or aggressive to the point of requiring immediate action (like goblins, trolls, knolls, demons, etc.) are going to be part of the story. It also leaves open the possibility of having a story element that goes against the tropes, the surprisingly-peaceful ogre, the demon deserter that wants to play for your team (how can you trust them? How do they eventually prove themselves. Do they turn on you?), etc.
Also, they would have just adopted a bear cub and raised it. There's no drama there.
Anyway, if that type of thing disturbs you, how did you get passed the creature
making undead (forgot it's name) to get to the troll?
