Law and order, as the term explains, is to ensure the obedience of one and that nobody dose anything to harm another or even commit a crime that betrays one's conscience.
I do agree that punishment is required to a certain extent so as to enforce the firmness of the government to protect the safety of the people under their charge. However, i do not agree to it being used as the main form of rehabilation process of a person when he or she commits a crime. This is because, the people that commit crimes usually only does that when they are left with no choice due to some causes they do not wish to go through. Who would enjoy going against their conscience or commit a crime and be indifferent after that?
Therefore, i believe that the most effective method to change the thinking of a person or help them out of their crisis is to talk to them, understand them and from there work out a solution to help them get through. Yes, punishment is inevitable, but it is to be used to a small extent and not as a method to force them to change for the better as it may cause them to become worse in terms of their conduct and mentality.
And of course, i would also not agree that any form of punishment in terms of maintaining law and order must be justified as laws are also written and passed by fellow human beings and it may contain mistakes in these laws too. I strongly disagree to the one life for another law where a murder will also be killed as a punishment for taking the life of another. Why do the judges have the authority to take alife of another when it is stated in their book of laws that it is very wrong to kill someone? Furthermore, there are many othjer ways you can punish someone, regardless of whether it is mentally or physically but i think killing someone for the mistake he have made is a little too much.
In conclusion, i strongly believe that certain principles of the present society should be revised and look into yet again so as not to slap our own face with our hands.
