Major detail missing from the international media's take on this: The guy hasn't been convicted as a criminal, but interned because he is deemed a risk to society. As such, he would normally have to be treated by trained professionals. Because of lack of place in specialized institutions, he has wound up in an ordinary prison, like some 1000 other internees in Belgium. At best he will be given some medication and occasionally get to talk to a psychologist, which of course in no way is a substitute for the sort of treatment he ought to be getting. He has repeatedly made clear that he would have dropped the procedure to obtain euthanasia if he would have been given access to the care he is legally entitled to. This is about as scandalous as it gets, and it very obviously should not be allowed to happen.
Glad to see you back, and this sounds worrying. They just want to give everyone an injection, don't they? Why wasn't he convicted?
In Belgium the court can either convict you to a fixed jail term or judge that you're not responsible for your acts and recommend that you be interned for an indeterminate amount of time to undergo treatment. If you ever find yourself standing trial in Belgium and your lawyer suggests pleading insanity, look for another lawyer because 1) you'll most likely still wind up in a normal prison and 2) 'indeterminate' often winds up meaning 'far longer than if you'd actually been convicted'.
Anyway, this little show has been called off for now because the doctor expected to carry out the execution has gotten cold feet and withdrawn from the whole sordid affair.
