We have to think of it like this. Your a Palestinian person living in Gaza w/o access to any of life's basic necessities. You lost some of your family members(children,wives,brothers,etc) to Israeli "Defense Force". What would you think if you were in this position?
2:194 The prohibited month for the prohibited month,- and so for all things prohibited,- there is the law of equality. If then any one transgresses the prohibition against you, transgress ye likewise against him. But fear Allah, and know that Allah is with those who restrain themselves.
2:178 O ye who believe! the law of equality is prescribed to you in cases of murder: the free for the free, the slave for the slave, the woman for the woman. But if any remission is made by the brother of the slain, then grant any reasonable demand, and compensate him with handsome gratitude, this is a concession and a Mercy from your Lord. After this whoever exceeds the limits shall be in grave penalty.
