Hey, I'm the Orc in question in this campaign, would love to thank everyone for their help with DM's concerns as well as add just a bit more information.
For alignment, yes I know that it's all very evil, but playing a full-blooded orc, I don't think it would have been terribly likely that I was born to a good family. I was raised with slavery, trained in torture, but never truly asked for any of it and moreso accepted it as life. When he was offered individuality though, he took it and went running. He isn't proud of what he's done, and part of him seeks to atone, but it was life to him. He enjoys the party for not fearing him and does what he can to protect them.
Alright, unnecessary defending aside,
I've talked with DM myself and explained that most of the anger I had was largely due to the fact that I kind of felt like my party wasn't as concerned with gathering information as I was. The only real ability at my disposal was intimidation and it was still poor. Despite my struggling and asking for aid, it seemed the oracle was dedicated to his "I don't like people" behavior and wouldn't assist with potential information. I didn't expect the newer players to jump right in, but I did hope I could rely on him for some assistance.
I have DM'd for this player myself on a few occasions, and it seems he always plays this sort of character, the antisocial kid that tries to fill in everybody's role in the party (Thus DM describing him as 'Gimmicky'), and it's become more than a mere nuisance over multiple games. He wants to play characters that have no reason to be with the party constantly, or who just hate the party, yet still act like top dog.
In this game even, something OP here and I have talked about that really irked the two of us is how he took a monster feat without permission and kind of began taunting DM about it. He qualified for Multiattack and took it. Neither I nor DM liked his behavior about how he almost acted like he outsmarted DM, and DM requested he take the Two-weapon fighting path instead. I can't help but feel as if this was the oracle using his longer experience to try and take advantage of DM. I may be thinking too deep here on that one, but in general, DM prefers if something 'unconventional' be brought to his attention before it's taken, and the behavior just seemed smug.
Anyways, this is just some extra information from a player's point of view. Dunno if it helps or not, but I know that DM appreciates it and as a DM myself I find it helpful as well.
