THERE are some people that you wish hadn't made it to rehab. Parasite junkies like Amy Winehouse's ex-husband Blake Fielder-Civil for one.
Vermin like him would have done the world a favour if one of his heroin hits had gone wrong and he was found lying stiff in the squalor where he belongs.
Because it is hard to imagine a lower form of human life than this shameless junkie scrounger.
It's not enough that he sponged off Amy for years and led her to the devastating heroin addiction that has wrecked one the most talented individuals we have seen for generations.
It's not enough that he gave Amy her first hit of heroin as they lay in bed after a coke-and- booze-fuelled bender.
Now this piece of scum has opened up about it all to a newspaper in a no- holds-barred exposé of the sex, drugs and rock'n'roll years that brought his wife to the brink of death.
And nowhere, nowhere in the screeds of crap spouted by this leech has he said the words: "I'm sorry."
Nowhere has he admitted that he ruined Amy's life - because that is exactly what he did. Nowhere has he taken responsibility for the evil disregard he showed for someone whose biggest mistake in her life was to fall in love with him.
Now, let's be honest here. This is a girl who clearly has the capacity to ruin her own life without needing any help.
An immensely gifted songwriter and performer hailed by her teachers as a teenager, there was, and still is, something about Amy that isn't quite wired up right.
It made me want to take him out and shoot him
You often see it in the most stunningly gifted artists down the generations - from writers to singers to actors.
There is a self-destruct button, and I think Amy's finger has probably always hovered over it.
She was already smoking cannabis and dabbling in coke by the time she met talentless chancer Fielder-Civil.
But to read his graphic account of how she became hooked on heroin after the first hit he gave her turned my stomach.
It made me want to take him out and shoot him. OK. He didn't force the heroin into her - that was her own stupid fault.
But he spotted her weakness and he exploited her. He talks about their junked-up benders like it was some sort of glamorous rollercoaster.
But the grim reality is that what happened between him and Amy that night when he fed her heroin is no different from the scene that is played out on a daily basis in squalid flats and squats all over the country - where a kid gets a hit for the first time and the downward spiral begins.
Fielder-Civil describes how Amy's eyes were rolling and how she begged for more drugs as though he was looking back on some drunken holiday high-jinks in Ibiza.
I cannot believe he is getting away with it. And the first thing I wondered is why is he not already in the pokey?
He has openly admitted in a newspaper interview to supplying someone with drugs, and furthermore he has admitted that she supplied drugs to him while he was in jail.
Why is he not now getting his collar felt by the police? He even brags about the songs from Amy's massive hit album Back To Black being inspired by him.
I would say shame on him - but I believe he has no shame.
He is no different from the skinny little addict toerag who pimps his girlfriendAnd he has the nerve to say that there was too much pressure on Amy, and that she needed to be given a break - when all the time he clung to her like the bloodsucking leech that he is, still feeding her with more heroin until she could barely find a way back.
Their story is no different from the broken families across the country.
I've sat in houses with mothers weeping into tea towels over the beloved kids they watched being swallowed up by heroin.
All of their stories began with a guy like Fielder-Civil. The graveyards and housing schemes are littered with junkies who got their first hit from a guy like him.
He is no different from the skinny little addict toerag who pimps his girlfriend in the streets of Glasgow for sex, while he hides in the shadows until she gets enough money for their next heroin hit.
He is no different from the guy who killed your son or daughter.
He is the lowest form of life. He may be now trying to get over his heroin addiction.
But it's just a pity that he even made it into rehab. Because this is one junkie we would have been well rid of.
