I believe that some people commit a crime out of jealousy or frustration. Others do differ. Certain people commit crimes and act on different behaviors under many different circumstances. People commit crimes by the individual free will. Chemical imbalances to the body and brain also have an impact on human behaviour and why people commit crimes. From experience being a teenager, I see quite a bit of 'peer pressure' not just towards me but to other people that I associate with and most times, words actually get to people and they give in and do whatever the person is trying to get them to do. Not often do you actually see someone walk away from the situation because they want to feel like they fit in, or be 'part of the group'. The reflection of how the child is brought up ( what kind of living environment as a child/role models at parents ) usually also shape the way that you turn out yourself as a parent.
*The crime that I had read is about a man who murdered his ex girlfriend and was also charged with three counts of sexual assault and two counts of breach of an undertaking!
Since this woman has custody of his two children and was not allowed to see him I think that he was frustrated with her and also had a bit of jelousy in regards to not being able to see his children. This mas was 32 and I do believe that he might have had other things in his life going on, not only the fact that he was not able to see this woman. Obviously other things had happened during their relationship that was not announced in the news article.
