Hacking group LulzSec taken down by own leader

From what I have read the hacking group LulzSec was brought down by funny enough its own leader. It has been reported that police on two continents took out top members of the group which was acted upon due to evidence given by the leader of the group who has been reportedly working with the government for months. Hector Xavier Monseur also known as Sabu is 28 years old and a father of 2 children lead the LulzSec group. So it looks like to get a better deal he decided to turn on his own kind to save himself. The interesting part about this is the fact a leader of a group was willing to turn everyone of the members in that were of worth, which makes me wonder what other hacking groups would be so fast to turn on their kin. Hackers do tons of things for different reasons and I suppose I shouldn’t be surprised that a hacker turned on their own, I just didn’t expect it to be a leader. Maybe a low level guy who worked his way up but the leader? That just makes me feel like it takes the law just one person to be arrested for a whole organization to go down. I can understand why Sabu would turn on his own, he had two kids, and needs to make sure they are cared for I suppose, at least that is why I would think he would turn in his own members.
