A nursery killer who carried out murders disguised as
Batman villain 'The Joker' told a court on Monday he was left "no choice" but to stab to death two toddlers and their minder at a Belgian creche -- despite saying he knew murder was wrong.
"I was aware that you should not (kill) but I did not see any other choice," Kim De Gelder told the court in Ghent, which is considering whether the 24-year-old can be held responsible for his knife rampage.
"I was pushed towards this choice, perhaps from outside. It came directly," De Gelder said in reply to lengthy questioning by the presiding judge.
De Gelder is charged with killing the two infants and their 54-year-old carer in an attack on the Fable Land nursery in the town of Dendermonde in January 2009, as well as the attempted murder of 22 others at the creche -- including 16 babies and toddlers.
De Gelder is further charged with murdering an elderly woman in a separate attack a week earlier.
The court must determine whether De Gelder can be considered sane or not. On Friday, his lawyer told the 12 jurors his client was a paranoid schizophrenic who "is irresponsible and cannot be punished."
Just after the release of cult 2008 Batman movie The Dark Knight, De Gelder entered the nursery with his hair dyed red and his face painted white with black around his eyes -- like the film's villain 'The Joker,' as played by the late Australian actor Heath Ledger.
Last year, US youth James Holmes was accused of killing 12 people and wounding 58 in a cinema screening the sequel of the film.
