Soulsteel is indeed steel made with tormented souls. As with demon summoning, using it or not is intended to be a meaningful, thematic decision for your character. If you allow the creation of soulsteel by other means in your game, I recommend that such alternate methods involve some equivalent sort of irrevocable harm.
