While some people argue genes can impact the criminal behaviors of human, others believe that situation is the reason of crimes. In my point of view, although gen is a significant thing, the circumstance could be more effective.
On the one hand, we know that genes are cause of the most behavior in human, as well as some illness in the body. Genes can influence in excellent or worse features of people. For instance, in a study conducted at 2010 about influencing of this parameter to commit crime, the scientists explored that, genes are involved in 50% of crimes.
On the other hand, the environment in which a person grows on it is very important.
Consider a person who is born in a family that one or both of his parents are criminals, it leads the person learn many kinds of crimes from his childhood and fixed in his mind. So, in this situation the probably that he will become a criminal in the future is high. Furthermore, the school where the person study and his friends are another case. If he has good or bad friends, this resulting in him become a criminal in the future or not. For example, if a boy has a friend who smoke marijuana, this leads to a negative impact on him, so, he will encourage to try this.
In conclusion, although some criminals are rooted in genes, I believe the situation and environment where a person grow on it has more impact on committing crimes.
