It's good to see an interesting poll once in a while, that is not "what iz yer favorite race / class / what should I take / will you use magic or weaponzzz" etc.
I think we don't know enough of the soul trapping mechanism actually, or even how a "soul" works. Is it only some kind of lifeforce ? Or does that mean the subject is still feeling, and living, and thinking ?
I made my answer based on pure hypothesis, that the soul is still feeling and thinking.
- Based on this, I don't trap humans, even evil ones, because then when they are dead and they caused so much pain and trouble, they should just be gone, not staying in this world inside a weapon or such, which gives them a second chance to wreak havoc. They should just be put at peace "you have done enough already, be gone forever now.".
- Animals, they are only reacting to instinct so I wouldn't trap them either. Even though one might think since they are just animals, they won't really realize their situation anyway, that doesn't absolve you from taking the decision to enslave a soul of an innocent living being, for your own personal gain.
- Spirits/undead : Same thing, they are basically souls already trapped inside a dead thing. Even if the soul is evil then the best thing to do is send them out from this world instead of keeping it in, even in a weapon. That being said, if they are going to be brought back in a lich anyway, I guess they could be trapped in a stone. Once again, it's hard without knowing undead mechanics
- Summoned : A summoned creature, the way I see it, is a creature borrowed/called from another plane of existence, and mind-enslaved for a moment (for most of them, some can't be enslaved). It's already bad enough to uproot a creature from its natural home and throw it into a fight for your own sake because you're too weak to do anything by yourself, if you're going to even trap its soul then it's way too much.
BUT of course, when playing the game, I'll consider that souls are only a lifeforce that is not thinking or feeling, so I will make soulstones out of anything :mohawk: Might roleplay a char that is against soul trapping though... could be interesting. And good old steel/silver plus skill moves means you don't have to rely on borrowed power. That would fit a 'good' char.
The above was only if it was like in real life, and with consideration that a soul exists and feels and such. Being agnostic, this is only pure crap for me IRL :rolleyes: Only needed to give some hope and prevent people with miserable life to get too depressed or rebel against power. But that's another topic
