We eventually find out that the reason Said actually killed himself is that he cannot bear to go back to the broken down war zone that he calls home, so in essence, it was rather an act of selfishness rather than that of a martyr. The one who manages to convince Khaled to turn is in fact the daughter of the leader of the martyrs Suha, daughter to Abu Salim. She explains that the more people martyr themselves the more people get hurt and the worse the situation gets for the ones who are left behind, families and friends.
It was not right of either of them to attempt to carry out their mission in the first place. Even the fact that Jamal decided their fate with the flip of a coin didn't make them reconsider. It shows how expendable people are to Salim. He will sacrafice everyone but himself to ensure the safety of his people, but his ignorance is that he cannot see , all these bombs are making things worse. The more people die in Israel, the more people are killed by the military in trying to find the culprits.
Khamed seemed to make the most sense out of things in the end. He didn't want to kill himself for no cause but to harm more than is needed and he knew this. In coming to this conclusion he decided that both Said and himself need to live. Unfortunately, Said, shrouded in his own perspective, decides to go on alone and die's for his own personal matters, namely the death of his father and the hell that he goes through every day when he returns home.
This film shows the reality to martyrs around the world, that they are doing things for a false cause, a cause which is not real, but a false hope of a paradise which does not exist.
"i'd rather have to live in the paradise in my head than go back to the refugee camp" Khaled.
