Will we be condemned for our eye-for-an-eye policy with Bin Laden or do we agree with Iran?

What Iran do and there laws are for the Iranians not for us to Judge, as long as they keep there barbaric cruel ways in Iran so be it, we in the west have no rights to interfere in others business, the English have in there past committed some horrific crimes against humanity during it historical past and we have moved on, these backward third world countries like Iran, Iraq and many others will also pass through this phase it is a normal progression, we were not invaded when religion ruled our lands and people were tortured, we interfere because we have forgotten our own history, this also applies to America, Canada and Australia, all the original inhabitants were almost wiped out by us so called civilized people from the west.
