Laws are needed to ensure people can lead a normal life without being disturbed by others. Laws also ensure that nobody is able to disturb the life of another without due reasons. To understand this, let us take a simple example of the traffic rule that every vehicle must stop at the red signal. If nobody will stop at the red signal, it will result in chaos. Nobody will be able to drive smoothly. Everyone would reach his destination after suffering for long hours. Laws are necessary to properly manage the administration. Hence, government needs to make rules for everyone.
