People who become murderers are not usually exposed to any more or fewer stressors in their life than other people (the majority of mankind) who are able to cope with those same stressors in a more rational manner.

Some people commit suicide. Some people join cults. And yes, some people when faced with stressors become murderers.

It's not the environment that creates them, it's the mechanism they've chosen to deal with the environment and there's not much of ANYTHING that you or society can (or should) be able to do about it.

Some people are simply unable to cope, and take to violence instead of reason.

So, yes, murderers can be people who are born with the inability to cope with stressors other than acting out violently.
