Reading the Player's Guide, they mention that in PFS "Killing
an innocent, wanton destruction, and other acts that can be construed as evil might be considered alignment infractions."
I think it's pretty clear that murdering peasants and burning down towns is evil. But are there any better guidelines for "other acts".
The reason I ask is because of some of my experiences at PFS tables. I've played with some DMs that seem to think killing your enemies is evil. For example:
In a recent game, our party faced a couple of troglidites. I hit the last one and put it down, the DM said that it was down but not dead. So I said, "I'll wiggle the axe a bit". Intimating that I will finish it off. The DM warned me that this was an evil act, and I would need to be careful. I asked why, and he said that it was a sentient creature that didn't need to die. Note, the troglidites attacked our party, we didn't seek them out.
While I agree with his statement: "it was a sentient creature that didn't need to die." I'm not playing a a Lawful Stupid Paladin, I'm playing a Lawful Neutral Fighter. Killing things that attack me or my party seems par for the course at that alignment.
Meanwhile, I've played with other DMs that don't have any issue with killing your enemies, or torture for information (as long as you can distract the Lawful Stupid among the party).
Another interesting example: My Lawful Neutral Dwarf has the trait "Lasting Grudge", Eg: He's Vengeful. In another game, there was another person left alive that attacked our group. In the end he was down, but technically alive. That dude had critted my Dwarf during that encounter. So my Dwarf made sure he died, satisfying his need for vengeance. Again, it was explained that I was being evil by seeking vengeance.
I played Living Greyhawk back in the Day, and I seem to remember that there was a far more specific and extensive list of Evil acts. But I certainly don't remember ever being chastised for killing my enemies.
I guess my overall question is, what options do I have here? I know I can just bring a Lawful Stupid Character to tables that have these DMs, or avoid those tables completely. But quite frankly, I'd rather alter the DMs behavior, treating the alignment system as so black and white isn't good for the depth of the game.
