Olympic athlete admitted to murdering his girlfriend

Oscar Pistorius admitted that he had killed his girlfriend Reeva Steenkamp. But the athlete underlined that he had shot her because he had mistaken her for an interferer.
Police officers try to determine why Oscar Pistorius really killed Reeva Steenkamp. They discovered anabolic steroids at the athlete’s home.
Since steroids have been discovered in Oscar’s bedroom, it would be possibly stated that steroids caused uncontrolled behavior in the sportsman. Anabolic steroids would be demonized for the murder.
In fact, you should recognize that it is quite hardly to claim that steroids are responsible for aggression and violence. Studies linked with this issue are quite limited. According to results of some researches, users of steroids are predisposed to aggression, paranoia, jealousy, etc. It is claimed that those who use steroids are more likely to commit crimes than those who have nothing to do with these preparations. But it is important to take into account that steroids may just contribute to aggression. Just these preparations alone can’t lead to aggression. They turn out to be only factors that contribute into uncontrolled aggression. Other factors should be also present in order to cause aggression. Circumstances play great role in such cases. So, it is even impossible to define whether steroids cause aggression or certain circumstances. Cases should be viewed as a complex of steroid use and circumstances.
It is also claimed by scientists that elevated levels of testosterone are associated with aggression in certain individuals. So, it is necessary to underline here that while certain individuals with elevated testosterone levels suffer from aggression, others with increased testosterone levels are not predisposed to uncontrolled aggression. This effect differs from one individual to another.
You can see that the connection between administration of steroids and violence is a complicated issue. Scientists have not studied this condition well enough to implicate 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 realize that they are going to utilize controversial affirmations.
