What would the gene be responsible for, &quot;Propensity to give a fuck about other living beings&quot;? Because in my mind, the line between being &quot;sane&quot; and killing everyone in sight is pretty fine.&lt;p&gt;One&apos;s logic could go like this, &quot;Man, everything sucks, and those kids down at the preschool are always so damn happy. Fuck Them. If I&apos;m not happy no ones gets to be  happy. Lock and load assholes.&quot; Suddenly you&apos;ve got another tragedy. I would imagine people that are suicidal sometimes feel like this. Maybe it depends on how introverted or extroverted they are. The introverts disappear quietly in the dead of night, and the extroverts start mowing down pedestrians in the town square and then blow their brains out standing on the Mayor&apos;s statue.&lt;p&gt;If a gene could be isolated for &quot;suicidal tendencies&quot; and also for intro/extro we might be able to reduce future events like this. But just because someone is a suicidal extrovert that hates everyone it doesn&apos;t necessarily mean they&apos;re going to start killing people. Maybe the ones that don&apos;t are just pussies and the gene for &quot;guts&quot; or &quot;courage&quot; would also have to be isolated?&lt;p&gt;I don&apos;t know I&apos;m just rambling. I ask myself why I don&apos;t kill my neighbors. Is it because I&apos;m &quot;sane&quot;? Well I guess so, if &quot;liking others&quot; and not wanting them to be sad is a characteristic of sane people. But I firmly believe that there&apos;s a tiny slice of murderer in all sane people, and I like to think of people like Adam Lanza as having just a bigger slice, because putting them in a different category of &quot;mentally ill&quot; sort of feels like I&apos;m denying a part of my own nature.</text><parent_chain><item><author>joonix</author><text>This may be politically incorrect to say right now, but I think the genes associated with mental illnesses that have a tendency to lead to violence will be phased out by a future generation sometime within this century and the next.&lt;p&gt;We&apos;ll soon enough try gun control.

We select our mates based on their phenotypes (like aggression, intelligence etc). It was more so in the past than now. People used to abandon infants that are born &quot;defective&quot; (we now have abortions). Parents selected the mates for their children because they are believed to be better judges of &quot;good&quot; phenotypes. It was customary to ensure that the family of the respective mate has no members with mental illness. Yet, after millennia of selective breeding, we still have all the crazies among us. The fact that those &quot;bad&quot; genes still exist must mean that they confer some benefits to the carrier.&lt;p&gt;The interplay between genes, RNA, proteins and other macromolecules is so complex that I doubt we can pin down a mental illness to a single gene or safely remove a mutation that causes mental illness from the gene pool without reducing other collateral beneficial traits.</text><parent_chain><item><author>joonix</author><text>This may be politically incorrect to say right now, but I think the genes associated with mental illnesses that have a tendency to lead to violence will be phased out by a future generation sometime within this century and the next.&lt;p&gt;We&apos;ll soon enough try gun control.
