Wyatt and his motivations...

So, I think it's fair to assume that Wyatt isn't really Wyatt, and the general really isn't a nobody. So far as I can gather from all the posts, Wyatt is actually Dolores, and the general is Arnold. What I haven't figured out, and maybe some body already did, is why Dolores kills Arnold. The only understanding that I have is that the show seems to hammer home that "pain sets you free".

Arnold (who wrote the prime directives it seems) could theoretically force Dolores to kill him, therefor removing her cornerstone. As seen with other characters, the memory of pain sets them outside of the their loop, thereby forwarding them towards sentience, whatever that is. Maybe I missed something, but that's what makes sense to me. Force her outside of her loop, to ensure that she sets in motion the events of the future?

And maybe that's why the MiB is untouchable as far as the park is concerned. If he knew that Dolores killed Arnold, unrestricted access to the park could be his reward for not speaking about it.
