You have absolutely no idea where he is at ! I've read tons of documents of that kind myself .... and this is also an interesting perspective.
Of course it's only one side of the coin, and maybe it'll take him some time to flip that coin. Maybe he'll never be able to do that, who knows.

Maybe you should also read some stuff on psychology:
when you've been deeply abused, before accusing the abuser, people who've been abused first try to find where is their fault, what is their responsability, what's wrong with them etc.
It's extremely difficult to start admitting the person you loved actually abused you.

Some people even NEVER reach that point ! It would bee too painful - for their own personal reasons. You should also respect this, and feel empathy for these poor guys. I do. I really feel very sorry for them, like the one you mentioned, and some people I know in real life.

For myself, I've been faced myself to some evidence of PR's abuses. And it took me months to understand what it meant. Maybe you can also look at it this way: the mass of evidence that's now available on EPO for instance can make it even more difficult to believe all of it is true ! That doesn't mean we should hide or remove any of it.
Reality and facts are sometimes very hard to confront.

Some people can, and it's a painful process. Some people won't. Some people will go back to the fold, some people won't try to analyze the whole thing and will leave the scene. You'll never hear about them aymore. Some people may feel extremely depressed .... and I hope they'll get help.
