The irony of hatred
The hatred seems like something is so wrong with other people that Atiq can't help but hate them, but actually, something is wrong in his own private understanding of reality. He can't help but feel like he is always the victim of fate, and this is the true ironic origin of his irony. Although he commits a murder in the name of God, he is clearly mad at his understand of God, or else, why the misanthropy?
The irony of community
Although a community typically represents level-headedness, and the willingness to hear other points of view, this novel shows the Taliban as the ironic opposite or inverse to real community. Because they all agree (no diversity), they just inflame their pre-existing ideas. They provoke each other to do violence.
The irony of the murder
There is no true belief at the bottom of Atiq's violence. In the name of God, he executes his understanding of justice against someone he feels absolutely disgust about. Therefore, he indulges in the most horrid, disgusting behavior of all: Murder by way of religious hypocrisy. He chooses to instate his own hatred as the standard for life and death.
The irony of prostitution
Although some passages in the Koran (and the Bible) make explicit commandments about prostitution and those caught in the act, those books are also written by men, and they do also include commandments about supporting one's community. No doubt, the prostitution in Kabul represents a chronic injustice against women, but the men see nothing wrong with their hatred.
The irony of terrorism
The sad truth about terrorism is that it is violence for violence's sake. Why do evil? Typically to get what a person wants, they might do evil, but this terrorist community constantly does evil for the sake of damaging others, out of a position of victimhood, as if they are finally getting vengeance against their community, but they are the problem of their community, not the victims.
