Of course (well, of course he differs with Cerberus. He still flies off in a Cerberus ship with a Cerberus crew wearing Cerberus clothes etc, so 'clearly leaves Cerberus' is a stretch). Because of this wonderful thing called 'free will'.Just owing someone your life does not automatically make you fanatically loyal to them, as Ironreaper suggested. If it did, Shepard would be fanatically loyal to Cerberus. He isn't, though, and I see no reason to assume that Cerberus members who joined Cerberus, not Commander Shepard, can be assumed to suddenly be willing to betray Cerberus and side with Shepard simply because he saved their lives. It doesn't make sense.
