In a patriarchal society like India women are considered as pride, prestige, and honour of clan. Reputation is the primary reason which lead to honour killing and give birth to a new crime. India acknowledging the largest democracy in world history, couldn't get women out of ancestral clutches where her fundamental rights and choice is overstepped. Even after 75 years of Independence of our country such enormity of honour killing still breathe in our society.

Our patriarchal community belief that a women righteousness, morality and rectitude belongs to her untorn hymen.
 
Honour killing is assassinating a person, who stands against the marriage arranged by the family or chooses to move her/his nuptial life as per her or his desire just because it brings shame to the family or community. They believe marriage or liking should be between people with same status, caste, and religion by choosing a person with different faith inflames disgrace to them such stigma gives validation to slaughter a man and snatch his rights and freedom to live. Honour killing violates article 14,15(1)&(3), 19,21 & 39(f) of Indian constitution.

The terror of losing reputation in the society involve mostly the male fellow of family to take the brutal act of honour killing in practice.
 
Inter caste marriages are the massive reason for honour killing in current scenario.

Case of Manoj-Babli the honour killing of newly wedded couple in 2007, from Karora village in Kaithal district, were brutally murdered by Babli's relatives. The crime was executed on the orders of a khap panchayat, for marrying in the same gotra. On June 23, two decomposed corpses were found from Barwala branch canal in Hissar.

 
Honour killing is mostly accelerated in north part of India Hariyana, Uttar Pradesh and Rajasthan. It not not only stick to the remote areas but in metropolitan area too. In 2008
Arushi talwar and Hemraj banjade case left the Nation terrified.

Conclusions:
Murder can never give rise to honour of family, it is absolute dominated under the title of religion or faith. Honour killing are brutal and disgraceful act which is still rooted in our society where basic human rights are shattered. Judiciary has played a vital role to punish the culprits but many a times such cases are not reported. Society need to be more enlightened on such end. Ethical value and tradition should not be used as a weapon.

Every person has right to live respectfully with his own decisions in life and nobody have the rights to overstep that.
