Will Oscar Pistorius’ lawyers argue that steroids have cause aggression in their client?

Oscar Pistorius acknowledged that he had murdered his girlfriend Reeva Steenkamp. But the athlete underlined that he had murdered her because he had mistaken her for  a burglar.
Police officers try to define why the Olympic athlete really murdered his girlfriend. They found anabolic steroids at the sportsman’s home.
Since anabolic steroids have been found in Oscar’s bedroom, it would be probably stated that steroids caused uncontrolled aggression in the athlete. Steroids would be blamed for the murder.
In fact, you should understand that it is quite hardly to state that steroids are responsible for aggression and violence. Studies connected with this issue are quite limited. According to results of several researches, users of steroids are predisposed to aggression, paranoia, jealousy, etc. It is claimed that those that take steroids are more likely to be involved in crimes than those who have nothing to do with these medicines. But it is important to consider that steroids may only contribute to aggression. Just these preparations alone can’t cause aggression. They turn out to be just contributive factors. Other factors should be also present for appearing of aggression. Circumstances play essential role in such situations. So, it is even impossible to determine whether steroids cause aggression or several circumstances. Violent cases should be reviewed as a complex of steroid use and circumstances.
It is also claimed by experts that enhanced testosterone levels are associated with aggression in several persons. So, it is necessary to notice here that while some individuals with increased levels of testosterone suffer from aggression, others with increased levels of testosterone are not predisposed to uncontrolled violence. This condition differs from one individual to another.
You can see that the link between intake of steroids and crimes is a complicated issue. Scientists have not studied this condition well enough to engage it. So, if defense lawyers of the Olympic athlete want to argue that anabolic steroids have made their client to kill his girlfriend, they should recognize that they are going to use controversial affirmations.
