Allthechickens - much research on the matter is now showing that those who claim to have been abused themselves are usually lying. They do it to gain sympathy or even in attempts to get lighter sentencing.
When therapists and psychiatrists deal with them once they are ordered to undergo treatment there's a lot of what they claim about the abuse they claim they also experienced which doesn't actually tie in with the experiences and reactions of those who have been abused.
And a significant number (usually when they're at a point where they know they'll never be released or are on death row) admit they lied about also being abuse victims.
Remember these are highly skilled manipulators you're talking about. They're often very charming, very believable people. That's how they get sympathy, it can also be how they get access to victims and how they silence victims.
It's not always done through fear but through emotional blackmail.
