If I'm being completely honest, I dont really believe we have free will. Or we do, but in an almost entirely meaningless way on a civilizational scale. While you might be able to make small choices, material conditions and the flow of history ultimately decide the course of your life. We're all just products of our environment which none of us can change on our own, and as much as we can change our environment as a collective is decided upon by current conditions which are determined by oast conditions, etc. Basically i think the entirity of history was determined at the big bang, and were all just along for the ride.
Sorry to triple reply, but with all that said, how can you ultimately blame people for their decisions assuming you're not spiritual and therefore see people as doing what they're "programmed to do" even if it's bad. Not to say you can't be angry by it, but I just can't seem to blame them if that makes sense.
