An eye for an eye should not be applied in the courts of law.
An eye for eye is metaphorical representation of pure justice. This is found in the law that was given to Moses. It simply means that if one kills intentionally, they should be killed too to serve justice.
However if an eye for an eye keeps on being applied in the courts of law, the chain of offence will not easily end due to jealousy and feelings of wanting to justified from both parties.
