yes, that picture IS ccreepy, and the dialogue on the right is, too. Does Alefantis still own that restaurant "Nalu Diner" in Berlin? As living in Berlin I could go there and have dinner (or better not)...
But in general we should be careful - not everyone who likes "weird" art - or even cruel, ugly, sexually pervert art...etc... IS also someone who is raping and killing kids. Yes, some people just like weird stuff!
And I think since the 60ties it's also some kind of "cool" to produce and also collect "weird" art. No one really liked the "nice" and beautiful art then. Artists wanted show us also the nasty and evil side of life.
Some people maybe are also dealing with their own bad experience in their childhood - and that's why they are into this kind of art.
Or maybe someone did get in touch with those evil +occult things - but was shocked and he did not go further! But he knows, if he's talking about it openly, he might get ridiculed in public or even killed - so he's putting it into the art.
We need more proof before telling, that someone is a perv and a child killer. A creepy art collection is not enough!
