So once a woman (or more rarely) a man, has committed these infractions of Allah's laws, of course they must be killed. It is what Allan the Moon God requires.
So it's not really an honor killing. It's more of an Islamic Killing, carried out by male relatives who have decided to be Allan's enforcers.
As stated in this Amnesty Report:
Among statutory laws, it is particularly two laws
which disadvantage women in Pakistan, both
introduced in the name of the Islamisation of law.
The 1990 law of Qisas and Diyat covers offences
relating to physical injury, manslaughter and
murder. The law reconceptualized the offences in
such a way that they are not directed against the
legal order of the state but against the victim. A
judge in the Supreme Court explained: “In Islam,
the individual victim or his heirs retain from the
beginning to the end entire control over the matter
including the crime and the criminal. They may not
report it, they may not prosecute the offender.
They may abandon prosecution of their free will.
They may pardon the criminal at any stage before
the execution of the sentence. They may accept
monetary or other compensation to purge the crime
and the criminal. They may compromise. They
may accept qisas [punishment equal to theoffence] from the criminal. The state cannot
impede but must do its best to assist them in
achieving their object and in appropriately
exercising their rights.”9
This reconceptualization of offences has sent the
signal that murders of family members are a family
affair and that prosecution and judicial redress are
not inevitable but may be negotiated.
The law of Qisas and Diyat prescribes that the
death penalty may not be imposed for murder as
either qisas [punishment equal to the offence
committed] or tazir [discretionary punishment,
when the evidence is insufficient to impose qisas]
when the wali [heir] of the victim is a direct
descendant of the offender. In such cases the
court may only impose a maximum of 14 years’
imprisonment.
Thus, if a man murders his wife with
whom he has a child, who then is the victim’s heir
and the descendent of the offender, he can at most
be sentenced to 14 years’ imprisonment.
Men who have killed their wives or daughters for
bringing shame on them could also in the past find
relief under the provision of "grave and sudden
provocation". Section 300(1) of the Pakistan Penal
Code (PPC) read: “Culpable homicide is not
murder if the offender, whilst deprived of the
power of self-control by grave and sudden
provocation, causes the death of the person who
gave the provocation...” The punishment for
manslaughter is imprisonment, for murder it is
death.
