Cardinal Kasper's Confusion

Cardinal Walter Kasper denies giving reporter Edward Pentin an interview after the conversation appeared on Zenit Oct. 15.  Yet the interview did take place. 
Pentin approached the cardinal outside the synod hall on Oct. 14.  The recording is here.
The problem is Pentin had identified himself at that time as a Register correspondent, which he is. And the Register did publish Pentin’s story with the Cardinal’s remarks (which can be read here).
Pentin is a freelance writer so he also pitches news to other outlets, including Zenit. After filing the story on the cardinal’s interview with the Register but before it was published online, he posted the transcript at Zenit. Pentin has since apologized for not making known to the cardinal his intention to publish at Zenit.
But the cardinal's confusion should end there. The cardinal was shocked that his words appeared at Zenit. But he shouldn’t be shocked by the interview’s content. The words are his — and now anyone can listen to them. Really the confusion is why would he say them?
