Agent smiths differ from the other Agents

[Valaro]

I like the point of maybe he hated humans for the fact that they all have a choice whereas as an Agent he doesn't.

I would say why is it possible for a Sentinel (The Agents of the Real) named the General and his bad ass group of mercs, capable of Entering The Matrix, and yet why would it not be possible for an Agent in the Matrix to do the same thing? Was there a way out? Were theses simply mind games set out by Smith? Or could it be that he wasn't aware of the "wow I got owned in The real lets all go to DA MATRICKS AND KICK JADA PINKETTS ASS IN THERE"! Concept?
