Ill set the scene. A party of 5 are adventuring. 1 dwarf, 3 humans and an elf. In the distance a party of 20 orks spots us and runs down the hill and attacks from above by dropping down up on us from around 10 foot up. We are fighting these when more turn up another 15 from a different position. they are places in an entangle, then a Steppe Troll turns up from above us and jumps over our party and attacks the orks that are in the entangle. He then stands there for the next 8-10 rounds picking off the orks. Not once coming towards us in anyway. Our mage decides to cast fire spells on the troll. It goes down but is regenerating. We then as a party finish off the 8 or so orks, the cleric then casts on the troll detect evil. Finds no evil. So the others in the party start to pour oil over it and burn the troll even though the troll is neutral at worse. Would a party who are not evil themselves do this or not. And would a Lawful Good Cleric like this idea or not. So over all killing a neutral troll that has shown nothing against the party had an alignment spell casts on it found it out to be non evil. Is that a good.neutral or evil act to kill it in cold blood when it was out cold on the floor. Can anyone clear up this for me please.
