A criminal is like a rotten apple among the good ones, he is like a virus to the society, which can even infect others of the same disease. Like a doctor excise any body part to save life of a patient likewise, a criminal is cut out permanently from the society for the well being of the society. Human beings live in civilized society and do not allow anyone to perform any inhuman act which causes harm or any type of discomfort to any individual. Capital Punishment is the best way to remove such diseased people from the society. Before they could spread their immoral believes to other people in order to justify their act they should be removed from the society from the “root level”.
In general, the jury may not be precluded from considering, and may not refuse to consider, any relevant mitigating evidence in determining whether capital punishment is the appropriate sentence for a particular defendant. However, the Eighth Amendment does not require courts to instruct a jury during the penalty phase that it has both an obligation and the authority to consider the mitigating factors deemed relevant by state law. Buchanan v. Angelone , 522 . 269, 118 S. Ct. 757, 139 L. Ed. 2d 702 (1998). Instead, it is sufficient for a court to instruct the jury that it must impose a life sentence if, after considering "all the evidence," the jury does not believe that capital punishment is justified.
