I've been thinking why I hate Michael. Not so much about his killing of Ana Lucia and Libby but more about that annoying attitude he had towards Sawyer when Others took Walt off the boat. I mean, you're trying to survive in the ocean on some torn piece of the boat in the middle of the night, Dharma shark's swimming just below you and the guy goes get off my boat. What boat?! Dude got some nerves.

So I don't know if it's a matter of betrayal or not, but I wouldn't be surprised if Michael's going to do something weird just for his own agenda. "I want my son!" seems to me just some facade for this guilt ridden egotistic semi father-figure.
