what makes someone DO something like this?

Y'all remember last year when the guy in Austria was found to have kept his daughter confined in the basement, and had fathered seven kids on her?

Here's another one: Man in Brazil jails daughter, has seven kids with her.

Even better, he's also accused of abusing one of the girls he had WITH his daughter. >_<

I simply do not understand what could make someone do this.
