Is this a serious conversation, I thought folk were just having a laugh. He acted like a right t**t. It worked. If the referee does not mind, then why should Krul? Honour/integrity? That went out the professional game a long time ago which is hardly surprising given the t**ts who run the game.
This for me. I can't even comprehend people getting on their high horse about a bit of gamesmanship from a keeper towards a penalty taker. The 'keeper is the one who is seriously disadvantaged - he is not expected to save it. Any kind of advantage from winding up the penalty taker (within the rules) is just part and parcel of the penalty/penalty shootout. If the ref doesn't see a problem with it - and he was right there - then what is the issue?
