Hey stop with the insults. Not condusive to discussion or trying to educate people or proving your argument right. Second, it is really weird when people discuss ethics in relation to global politics because even the people you believe are good do horrible things. Are we going to say that killing innocent people is evil regardless of any so called justification? Then you can't turn back and support people who do that same thing. However on that grounds you can't support ISIS because you think their actions are justified then come for US and US allies because they're doing the same thing. Also, what does ISIS actually want? Like I get the they hate the west aspect. But like what is end goal for ISIS?
Remove western influence from the region I'd imagine. Unless there is a greater religious goal but I doubt that, I think religion is used as the guise for their actions.
