I'm afraid you are oversimplifying this a bit. I don't believe this is what Benzo was saying. He's saying that if that indeed happens, it's "mankind's" fault, or the original opposer who is currently the ruler of this system of thing's fault. God is righteous, and cannot be involved with unrighteousness. He doesn't specifically take the lives away, unless those ones are under judgement by him. Among examples in the bible, we can find that the ancient world before the flood was under judgement by him, along with those in Sodom and Gomorrah (spelling?). Also those destroyed at the future guaranteed Armageddon are said to be under his judgement. This isn't a war that happens from mankind starting a nuclear war, but the direct result of a decision by God to destroy the wicked. However all the bad things that have happened, resulting in pain, heartache, bad consequences and ultimately death in this system of things, as a result of mankinds original sin have come about as a result of that original opposer, and the willful sin of our original human parents. God allows this to go on, but doesn't support it, or authorize it. In fact He says this will be a thing of the past where the idea will never even come up into mind. You personally may blame God for the attrocities that have happened for the last few thousand years, but that doesn't mean you're correct in your assumptions. Many children from the dawn of time have blamed parents for one thing or another without cause. However coming to know the real facts behind decisions made will go a long way to learning the truth of a matter. I implore you to learn why things are as they are instead of just allowing yourself to form an opinion without the full facts. Jehovah's Witnesses are active in every nation on earth teaching people from the bible, reasoning from the scriptures, helping people to come to a better understanding of God's purposes, and the future of mankind. Ask one the next time they come by any of the questions that have been brought up in this thread. If you truly want the answers, and are willing to hear the bible's viewpoint, you might learn something new. The Apostle John was inspired to write at John 17:3 "This means everlasting life, their taking in knowledge of you, the only true God, and of the one whom you sent forth, Jesus Christ." So your eternal welfare is at stake, whether you want to believe it or not, depending upon your decision here. Will you learn about Him, and Jesus ..... or not?
Edit: Yes, I guess I can come forward and say that I'm one of Jehovah's Witnesses. I wish I knew as much today as I did years ago regarding religion, God, and the bible, but my mind isn't as sharp as it once was, and I can't say my attendance at the meetings is as strong as it once was. However I have many publications at my disposal from different sources to help if I need it. I don't know much of Hinduism, or Muslim religions, but I have had some experience with "Christian" religions. And since I'm a firm believer in the bible, I tend to repudiate evolution. However I will never try to force anyone to "believe" in something against their will. If God draws you to learn about him, then it's to his glory. In fact I would be a terrible person to look to for answers, and to emulate. But in any case I hope you do find your way to learning about God. I can't stress the importance of doing so enough.
