Most interesting thing to me about the word as we know it, is that it provides the fastest track imaginable to full denial of God. And what an incredibly backward process it must be for a person to use the failures of man to deny God. But it's exactly what happens, every day. All that's required is to point at others and say, "see!"
Worst tragedy ever, then, is someone's conscious decision to exclude God from knowledge - due to the behavior of man. It's like: wtf, over? how's that?
And btw, if you go so far as to "decide" this as your truth, for any reason you might claim, then you've made it much more difficult to go forward with a clear mind: the exact opposite of what you'd hoped for. Again, dumb. That's because whatever caused you think it'd make you better, smarter, faster, less bothered and more complete, to deny God, then becomes threatened by the empty worthless decision you made, should you otherwise broaden your senses as you live life. And the best always do. So don't pretend to read the future by locking yourself into something so impossibly close-minded.
You're doing everything in the negative, that you accuse the believers of doing in the positive.
