Advantages of honour
1 - Self-awareness/pride
In societies which are ordered around ideas of honour, upholding
perceived standards of behaviour can become the basis of a person’s
identity and positive self-image.
2 - Increased security and prospects for offspring
Families which conform to accepted standards of honour and moral
behaviour receive benefits in terms of a better future for their sons
who enjoy increased marriage and career prospects within their community.
3 - Improved contacts and business opportunities
Families which publicly uphold their honour usually gain increased social
status. This can result in better contacts within the community
which can lead to material benefits such as increased income for the
self-employed and greater trade for owners of shops and businesses.
4 - Providing stability in an changing/new environment
For immigrants arriving in the UK, vesting one’s identity in intangibles
such as traditional ideas of honour and pride can be safer than rooting
one’s reputation and social worth in terms of property, wealth and a
career.
4 - Sense of superiority (vis-à-vis members of other ethnic
groups, castes, religions)
For immigrants with low career prospects, investing in ideas of sexual
honour can provide a way to feel superior to strangers by measuring.
It is incredible that brutal (as is often the case) murder is considered to be an act that carries no dishonour. Then clearly protecting the existing culture is a major reason for such killings
Common ways in which honour can be damaged
1 - Defying parental authority
In many cultures, elder members of the family are expected to control
their children. Parents who publicly fail to do so may lose status in the
community as a result.
2 - Becoming ‘western’ (clothes, behaviour, attitude)
People from honour-based cultures often transform ideas of honour
into a pride in one’s origins and/or religion once they settle in ‘the
West’. Families who allow their children to assimilate into wider society
can be seen as betraying their origins, their community and their
ancestors.
3 - Women having sex/relationships before marriage
Many honour-based cultures put a high premium on a girl’s virginity
and sexual fidelity. Families whose women are believed to have extramarital
relationships (even of a non-sexual kind) can suffer a decline in
honour and social standing.
4- Use of drugs or alcohol
Drinking alcohol and using drugs not endorsed by religion, culture or
tradition can bring shame on families because their children are seen
as abandoning or rejecting the values of their parents and their community.
5 - Gossip
In many cases honour is damaged less by a person’s action than by
knowledge of that action becoming public knowledge. Rumours and
gossip – even if untrue – can damage the status of a family or an individual.
Lastly
"In many cases, families are less concerned with immoral acts, than with how these will affect how they are seen by their relatives and by other members of their community. As honour is an intangible asset dependent on a community’s perceptions, an ‘immoral’ act does not become shameful’ or ‘dishonourable’ until it becomes public knowledge. The consequences of damaging one’s honour or the honour of one’s family can be serious."
