Hentai objectification vs instinct

The questionability of women portrayed as being used only for sex, and the human desire to use women only for sex.  Both go against our "civilized" mindset, yet are natural feelings.  Perhaps this conflict between what we see as lawfully or ethically right vs what we see as naturally or instinctively right, is what makes hentai so powerful a combination. 

In other words, how can this be wrong when it feels so right?

I read about a simple test once done about honesty involving an office, cookies, and people choosing to pay as they eat. It turned out the guy made back 97% of the cost of the cookies.

If you have ever been to a Sikh eating place, they have a "pay by conscience" system where you eat for as little or as much as you like. Very good if you are student.
