I would tend to take issue with the one character that CDGed you when everyone else was just trying to subdue you. But the same goes to you as well. Why couldn't you have taken out Anea with subdual damage? You can't expect the party to give you any benefit-of-the-doubt that you didn't give them.
This was essentially Mossimo's player's argument. Subdual damage doesn't seem to be apt in a rage, though I have been rethinking whether or not disabling her then dropping my spear and raising my arms might have been the better option. In previous games, even though we roleplay, we tend to give a higher respect to someone's PC than an NPC - especially an NPC that was hostile to the party previously!
Help your friends - Your character made a plan with his theoretical friends and then went directly against it. Earlier you had shown yourself to be trigger happy (something is following us, KILL IT!) which is not that helpful to your friends, and stubborn about going along with group plans (the whole covered wagon issue.)
I reject that my actions were trigger happy, though that is how the group perceived my character. Something was following us (poorly), we all noticed it. The DM asked if anyone wanted to do anything and no one said anything, so I replied that I take a spot check to get a good look at it. I roll and see a goblin. The party has been fighting groups of goblins since the first session, so I take out my longbow and shoot it (it spent the round I spent spotting it running away). I shot it once and it kept running, so I shot again. During this entire sequence the group literally did nothing, waiting to see what would happen. After it fell to the ground, they surged forward to interrogate it, which I approved of.
Thus, by wounding a goblin spy I was not acting like a psychopath, I was saving us from an ambush up the road. After we had that information, the goblin began pleading for its life and such so I said just kill it (ie- mercy). The group decided to use it as a decoy to try and fool the goblins/ogres up the road. After that battle, the goblin offered up some more information - about a possible alliance with the goblins. The party rejected this idea, but wanted to keep the goblin just in case he could come in handy again. Further, since we we found a letter detailing the appearance of me and another PC, we decided to use a covered wagon to avoid further ambushes. My character objected to being in a covered wagon for hours with a gagged and bound goblin, so Mossimo's PC strapped him to his donkey and explained he would unstrap him at intervals to feed him, let him use the bathroom, etc.
Maybe I was "bloodthirsty" or "trigger happy", but this was an enemy scout not some unknown possibly peace-loving goblin.
Kill the bad guys - The group had decided that someone wasn't a bad guy and you decided on your own to kill her anyway.
She was previously against the group, trying to arrest one of the PCs that my character had known the longest. I had a personal vendetta against her which I admit I should have revealed before the fight. The group was planning on blackmailing her for aid (ie- if you don't help us, we'll kill you). This was a mistake on my part.
Roleplay interesting characters - there isn't actually anything interesting about making a plan then going against it to anyone but the person doing it.
Really? What about the motivations that led to such aberrant behavior? I would be curious if something like this happened in a game for the reasons why. I think character motivations can and should be involved in the story, integrally if possible. Was it risky and a little underhanded? Yes. Uninteresting? Not in my opinion.
You may well have a group that has the same goals you are talking about - and thus reacted badly to your behavior.
I don't think CDG a PC over an NPC most of the party has never met and has little to no reason to trust qualifies as "help your friends", but that's just me.
Thanks for all the responses, by the way. I am feeling better about the whole situation and the continual reassessment is making it easy to see ways I could have accomplished my goals in a more friendly way.
