Do you think that laws alone can curb social evils or is social awareness also needed to change the mindset of the people?

No, laws alone are not sufficient to curb social evils. Although, this is the first step towards a radical change, so it is the duty of the government to introduce this in the country. But at the same time, they must also create enough social awareness so that the people can understand the difference between right and wrong. The people should also try to spread the word so that the general mindset of society is changed.
