As O’Brien questions Winston and Julia he asks if they are prepared to commit murder, and they agree.
He asks; “‘To commit acts of sabotage which may cause the death of hundreds of innocent people?”
To which they immediately agree, as they do to betraying their country and “… cheat, to forge, to blackmail, to corrupt the minds of children, to distribute habit-forming drugs, to encourage prostitution, to disseminate venereal diseases — to do anything…to cause demoralization and weaken the power of the Party?'”
And without hesitation they agree.
Then O’Brien asks: “‘If, for example, it would somehow serve our interests to throw sulphuric acid in a child’s face — are you prepared to do that?”
Without pause, they agree.
