The child abusers are almost useless, the children abused struggle to make their way.

Yes something has afflicted these child abusers with near uselessness.

And yes the children who were abused struggle to make their way too.

It seems to be the case the children might be more useful when they get some justice, some help.

The child abusers are a waste of space, only good for spreading more child abuse and drug addiction.

They can barely hold down a job as a janitor in a shop, or a young one , perhaps a steward on a ship.
