Did steroids cause violent behavior in Oscar Pistorius?

Oscar Pistorius acknowledged that he had murdered his girlfriend Reeva Steenkamp. But the athlete underlined that he had shot her because he had mistaken her for a thief.
Police officers try to define why Oscar Pistorius really murdered Reeva Steenkamp. They found anabolic steroids at the athlete’s home.
Since anabolic steroids have been found in Oscar’s bedroom, it would be probably argued that steroids caused uncontrolled violent behavior in the athlete. Steroids would be demonized for the murder.
Actually, you should comprehend that it is quite hardly to state that steroids are responsible for aggression and violent behavior. Studies linked 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 who apply steroids are more likely to be involved in crimes than those that have nothing to do with these medicines. But it is important to take into account that anabolic steroids may just contribute to aggression. Only these medications alone can’t cause aggression. They turn out to be only factors that contribute into uncontrolled aggression. Other factors should be also present for appearing of aggression. Circumstances play essential role in such cases. So, it is even impossible to determine whether anabolic steroids cause aggression or several circumstances. Cases should be reviewed as a complex of steroid use and circumstances.
It is also stated by experts that enhanced testosterone levels are associated with aggression in certain individuals. Thus, it is important to specify here that while several persons with enhanced testosterone levels suffer from aggression, others with elevated levels of testosterone are not predisposed to uncontrolled violence. This condition differs from one person to another.
You can see that the link between application of steroids and violence is a complicated issue. Specialists have not studied this condition well enough to engage it. Thus, if defense lawyers of the Olympic athlete desire to argue that anabolic steroids have made their client to murder his girlfriend, they should understand that they are going to use controversial affirmations.
