Maybe the study could measure the area of the brain, dealing with pleasure?

It was reported that violent video games, was a steady diet of Adam Lanza?

Would it be any wonder that he delighted in violence?

Maybe he spoke of this love or desire for more? 

Maybe a red flag should have gone off?

But why wait to examine the DNA from a corpse

Test the young earlier in their lives, for possible defects. Hook em up and see what areas of the brain are stimulated, under certain conditions.  A sort of Rorschach test could be developed, to ascertain if this person is susceptible to either pleasure or abhorrence.

Before a felon is released from incarceration, through a pardon, see if these brain activities, would ascertain, that the offender sill delights in their previous bad tendencies.

I also do believe, it is possible, to identify people with a propensity, to do bad things.

If one sees individuals, that frequents bars, or constantly talks about going to the bar, one might assume this person is possibly a drunk. Would it surprise someone, if this person were to drive while intoxicated and could be a threat?

Or people, who feed themselves, on a steady diet of pornography, and every conversation with these individuals, are about sexual matters. Would one be surprised, that such a person could commit a sexual assault?  A date rape possibly?  

Or people who speak hurtful things, could they DO hurtful things to others?

If all a person does is talk about their riches, can one assume that person is greedy? Could they have a propensity to steal to satisfy their greed?

An old parable states “For out of the mouth, the heart speaks”

For wherever the treasure is, that’s where their heart is

Wherever their heart is, you’ll know, they’ll speak of it.

We have to stop ignoring the signs.

The idea and promotion of letting each person “do their own thing” or the promotion of ”Whatever floats your boat”  is not the best thing, for a civil society.

If the reports are true, Adam Lanza did do his own thing and he enjoyed violence.

The firemen’s murderer did float his own boat. He enjoyed killing.
