I symphatize with your approach, I just happen to think it's pretty optimistic in this case. In the end, maybe all one can conclusively say here is that the future will show how things really are? And even then it could be argued that actually his project stretches from generation to generation and only reveals its motivations and intended goals in the year 2222, or year 5555, and even then it might be just a big project with nothing special to offer, and we will never know.
The way I see it, first, what Jim is doing here is very very easy, there's just nothing to it. What do you suppose could potentially come out of this? To answer your question, I would have approached Carlos and Banacheck just like I'm approaching Jim now, what they say and how they act, is how I think of them, at every single point of the way, wherever my current information leads me.
I don't know, I just wrote a big chunk of text about this but decided to delete it. I just think that it is reasonable to form opinions about a person by the way they act in the real world. Currently the picture I have of Jim is not too positive. I'll just update my view on him if there ever comes a good reason for that, I have to go by the data currently available, even if it will always be limited.
