"The gunman can repent, beg forgiveness, ask Christ to be his Savior, believe and be forgiven,
Then should his flesh be convicted and executed, he will walk into the presence of the Lord" - The fact that they honestly don't see anything wrong with this is rather frightening. And then they dare say atheists don't have morality.
"They already face an eternity of condemnation without God." - So...You're saying murder is only bad if it isn't done in the name of your religion? Pal, let me introduce you to these kind people of ISIS who think the same. I'm sure you'll get along great.
"God Who spared no expense..." - Okay, first, what expense? No, seriously, what has god ever had to give up?
Anyway, for an omnipotent being god has hardly done anything to help us for something that was his fault only. If he honestly wants to save us, he should stop sending us to hell for something beyond our control. Something our very distant ancestors did 'cause god was too lazy to put a fence around a single apple tree. If he hates sin that much he shouldn't have made it in the first place. If he didn't want humans to have it, he shouldn't have put it in clear view and reach of what are essentially children.
And since he did, it's HIS responsibility to clean up the mess. His alone! If he hates sin, he should just cure us and destroy it. After all, shouldn't a tumor be removed from a cancer patient instead of letting him live in misery? If he wants us to go to heaven, then just rewrite his own rules so that only the genuine good people enter.
Look, fundies, in the end god is the one who sends you to hell. Not the victim himself, not satan, only god himself. If he doesn't want us to suffer, he simply should stop doing that. It's really that simple.
But let's see, what your god could do better: Just remove sin from us (shouldn't be difficult if that's what we're supposed to be);
stop letting morons, bigots and murderers preach in his name and just say the actual truth himself;
Just reveal himself to the world to remove all doubt, thereby increasing the people who accept "salvation";
give actual proof that the bible is 100% true, and remove all "false evidence";
while we're at it: write a decent, consitent, very clear bible;
pardon all of us instead of exclusively those who brownnose him;
change the rules he himself made and make them a lot better;
stop letting bad things happen to good people;
destroy satan if he's the cause of all misery (which I severely doubt);
That enough for you?
