It is actually not surprising to me that alot of individuals on the death row do really have some low cognitive functioning, or mental illness, or some head injuries,or some brain damage, or some fetal alcohol syndrome, or some kind of serious trauma, or some other possible "bad brain" problems... Many of these people were also horribly victimized when they were kids, which is just a single fact among many other facts,the victimization messes with the heads of those individuals...

The fact is that most People with the normal right mental capacity do not actually generally commit the crimes which are "worst of the worst" crimes... People who actually think straight do not actually become serial killers, or they do not torture anyone intentionally.., etc. Some may seem to look or feel smart in terms of an IQ, but the fact is that their thinking is still broken.....

We also have to really remember this when we considering the prevention question: who are we actually trying to reach?the truth is You and I might really be deterred by a capital punishment such as death penalty, but then again, i feel society do not really need the death penalty to deter an individual...because even without it, we are actually not going on some kind of shooting spree....i believe those people that the society is trying to reach by creating the dealth penalty are those individuals who might really commit these worst crimes....

but another fact is that most Potential perpetrators of these dangerous and horrific crimes are frequently or often unable to actually connect the right dots properly between an instant choice and also the actual deterring punishment.... To be really deterred by a death penalty then they must also actually realize that there is a chance that they will get caught and that the jury of peers would actually not in fact see the situation in a sympathetic manner.... Many of these actual true heinous crimes are really committed under an influence of some powerful drugs and/or emotions, which are also barriers to a clear reasoning.....
