Role of steroids in murder committed by Olympic athlete

Oscar Pistorius acknowledged that he had murdered his girlfriend Reeva Steenkamp. But the sportsperson claimed that he had killed her because he had mistaken her for a thief.
Police officers try to determine why the Olympic athlete really killed his girlfriend. They discovered anabolic steroids at the sportsman’s home.
Since steroids have been discovered in Oscar’s bedroom, it would be probably stated that steroids caused uncontrolled aggression in the sportsman. Steroids would be blamed for the murder.
Actually, you should comprehend that it is quite hardly to claim that anabolic steroids are responsible for aggression and violence. Researches related to this issue are quite limited. According to results of certain studies, users of steroids are predisposed to aggression, paranoia, jealousy, etc. It is stated that those that use anabolic steroids are more likely to commit crimes than those who have nothing to do with these products. But it is important to consider that steroids may only contribute to aggression. Only these preparations alone can’t cause aggression. They turn out to be only contributive factors. Other factors should be also present in order to cause aggression. Circumstances play great role in such situations. So, it is even impossible to define whether steroids cause aggression or several circumstances. Violent cases should be reviewed as a complex of steroid use and circumstances.
It is also stated by experts that high levels of testosterone are connected with aggression in several individuals. Thus, it is important to notice here that while certain individuals with increased levels of testosterone experience aggression, others with high levels of testosterone are not predisposed to uncontrolled aggression. This condition differs from one person to another.
You can note that the connection between steroid use and crimes is a complicated issue. Scientists have not studied this condition well enough to implicate it. Thus, if defense lawyers of the Olympic athlete want to argue that anabolic steroids have made their client to murder his girlfriend, they should comprehend that they are going to utilize controversial affirmations.
