Should sellers of homes be obliged to report the spiritual or criminal history of the property?

Many state laws require that "stigmatized" properties, such as those with a history of paranormal activity or a past owner such as Jeffrey Dahmer, be reported by real estate agents. That leads to the home being devalued in price. Should such a law exist? Moreover, should potential buyers take advantage of any "stigmatized" property, thereby offering and paying less, even though belief in paranormal activity is irrational?
