Do you think that there is a genetic link towards being a serial killer? If so, do you think that jobs and colleges someday will be allowed to scan for those genes? Or is this considered genetic discrimination?

So it would be nearly impossible to based on genetics alone, identify anyone with any type of criminal motives.
