Roy/Aaron: illogical twist [SPOILERS]

The thing is, we have no idea what Roy/Aaron's real motive was for the murders. The fact than there is no Aaron, just like there is no Verbal Kint in The Usual Suspects, changes the reality of everything we saw and everything we think we know. It could be that Roy/Aaron participated in "Purging the Devil" of his own free will, and enjoyed it. And perhaps had some other reason for killing Rushman and Linda. So I'm not so sure that there's anything illogical about the final twist.

The Falcon flies

I think the book went more in depth with this, but it's been over a decade since I've read it. I believe Roy had his own motives for letting things play out the way they did (even if it was just meanness). William Diehl was the author, if you're curious about the book.

you need to watch again and understand where Marty uses the mysterious Michael O'Donnell as what lawyers call a Blue Horse.

then you will remember the "bad bad thing" Marty did, as told in bar scene

Marty, 10 years back, had obeyed his boss "Shawn-Assy" [I assume a deliberate anagram] and dropped all charges against archbishop in the O'Donnell case [and by inference Roy was just one more of his numerous pedophile victims]

so Roy decided if the law had failed them HE would do the job FOR them, and practiced the Aaron character for years on end.

get the picture? this is very similar to motive in The Sixth Sense where Vincent at age 10 is similarly abused [but with Zoloft] by the shrink and comes back at 18 or so to KILL him.

now read on as they say [but ask if you need more help]

ie the forced sex was WAAAAY after the fact
