I see. And how would you have him develop as a character? I am assuming you asked your original question because you were trying to get a picture of what the Na'vi would think of him. If he doesn't change his attitude, then they wouldn't think twice to get rid of him if they got the chance; that is what I think.
This kind of reminds me of my own fan fiction story, where I have a character named Walter Lockwood. In his youth he was idealistic about going to Pandora and communicating with the Na'vi through music and other peaceful activities, but the situation on Earth eventually turned him into a stone cold soldier with an almost unlimited motivational drive. He basically only lives to save humanity as he sees it, but has sunken so deep that by the time he comes face to face with a (pacifistic) Na'vi, the only thing he can do is aim his weapon and coldly offer the choice of death or surrender. When the Na'vi surrenders, he takes her as a prisoner and he subsequently vents his opinions to her in a show of intimidation. It shows how far he has fallen from his original idealism.
That sounds very interesting because usually the first thing that dies is idealism. I would really like to read your story.<3
That said, i agree with you that most Na'vi would indeed try to get rid of Erik is they got the chance. So far im still working on his development arc and would like to tell you how his first "close encounter" with a Na'vi goes. Let me explain in short...this is the intro of his encounter, i want excuse the bad english, im not native english speaker. I am currently draw the storyboards for this but wrote down the script for you here and super happy about your opinion.
"He is very frustrated about his botched mission and the criticism he got. He decides to go alone to that area that they had to leave to retrieve some equipment. He leaves Bridgehead unauthorized and while flying encounters more and more technical issues on his craft. His left engine having a failure cascade that leads to an uncontrolled spin of the aircraft and ultimately to its crash landing in a coastal jungle region.
He is dizzy and disoriented but able to grab his breathing mask as the fuselage fills with smoke. He tries to open the door but its bend and doesnt move an inch. He notices that the back of the aircraft is burning, the right engine still running and the engines blades constantly ripping through the metal case holding it in place.
He is trapped and starts to hecticly run in few circles trying to figure out how he can get out, swearing in german / english words. He presses his shoulders against a panel and pushs with all his strength against the windowframe, desperatly pushing and kicking.
Meanwhile a group of Na'vi heared the thundering explosion sounds and the screeching engine, they carefully come closer and see the burning wreckage. They keep their distance and cant decide what to do. The group leader indicates to leave and almost all of the group move on...except one of them...she first follows her group but then slows down and diverts her route back to the wreckage...
Inside Erik is still kicking against some windowframe, when it suddenly shatters, to his suprise he is grabbed by his collar and pulled out. He stares at her with big eyes while his mind is trying to cope whats going on. He starts to shiver as he realizes what just happened and in what situation he just went in. For him its now even worse than before and he tries to grab his gun....she tries to hold his arm but he is strong and able to push her away.
She is a pacifist and absolutely disagrees in hurting or even killing sentinent beings. She has great empathy, thats why she pulled him out in the first place. She feels that this guy is driven by fear and not rational...but she also notices that he is not shooting...she aims with her bow at him and its a standoff...but when she goes closer....he retreats to keep distance, while screaming at her and angrily shouting. She somehow has to think that its interesting and kinda ironic, that with all his tech and imagined development...he behaves now exactly as any other cornered being.
His thoughts are quite different from her...mix of absolute aggression, fear and unstable panic...but he also underlying thinks why she pulled him out and did not kill him instantly, a thought that confuses him...his thoughts about this stop when he suddenly cant retreat any further and his shoulders bump into part of the wreck...he stares at her with wide eyes and also stops shouting but still pointing his gun at her...she stands still too but slowly puts her bow down, holding her hand infront her and indicating him to calm down...
He keeps staring at her...still thinking about what situation he is in...his technology brought him here, human smartness created all those incredible things...but it also failed and now he stands here, facing extreme danger, trapped in a hostile environment, lost and alone...well not alone anymore but he is very unsure if this company means good or bad...he figures how ironic this is...since it somehow mirrors the problems and situation all of humanity faces right now. Tears run down his face but he also giggles about that irony...he lowers his gun too but just keeps looking on her while sweeping tears away.
She decides to get closer and senses that this guy is no danger. She carefully watchs him and his reactions...she still has her left hand at her knife...but tries to avoid him seeing that, she looks into his eyes as she gets closer and reaches her hand out. He let it happen as she grabs his right wrist to get the weapon from him...once she achieved that she throws the gun away...while still holding his arm she looks him in the eyes...she has never seen one of the sky people so close...she sees his face through the glass of his mask....and over it the reflection of her own face..."
