The guy brought down an OC administration and, theoretically, ceased criminal activities himself.

The feds set him and his family up with employment and a new life in a nice part of the country, certainly no backwoods shithole, and such was his natural proclivity towards crime he ended up getting his entire family jammed up again.

What more can they do?

These people are incapable of working hard for a living.

It's the same with Joe De Fede moaning about the Feds not financially babysitting him for the rest of his life. Other rats like Massino and Leonetti were allowed to keep money that should've been repatriated.

The co-operation of rats is intrinsic to getting these vermin off the streets.

It's not unique to OC.

In the UK, a huge pedo ring was brought down thanks to a cooperating pedo and he didn't get ANY jail time.

I invoke my right under the 5th amendment of the United States constitution and decline to answer the question.
