Cypherities baby, through and through!
As Roukan points out in the presence of a truce our options are open, I would probably work for the Merovingian - I am no wannabe hero or crusader.
In the absence of a truce (where we are today) survival dictates only two credible directions - try to hide within the Mero organisation or fight for you right to continue in Zion.... imo at a genuine realistic level there is zero credibility in working for the machines in any way.... Obstinate and excessively pessimistic I would therefore reluctantly join Zion.
I'd just be a Bluepill. =P
Zion all the way but I would be for peace like neo was! in the end!
