A. Men are born inherently separated from God, and born into a sinful world, giving them a sinful nature. Men are thus prone to wickedness. Prone to sin = inherently evil, by definition of evil as the opposite of benevolence, characterized in God, of which we are separate from.
Yes, I am inherently prone to want to look at the porn on the web and commit adultery (which also means sexual immorality), I am inherently prone to, though knowing I should not, talk trash and blaspheme about people (commonly known as gossip)... I feel a strong desire to do such things... Of course, in every second of your life you aren't trying to find ways to sin, but you and I will invariably do things we know we shouldn't.
B. EXACTLY! Religion, in and of itself a GOOD thing, has been used by manipulative people to control people. This is not because religion is set up to do it, it's because people are inherently wicked, and in large groups, incredibly gullible, ESPECIALLY if you do not know that which you are supposedly believing. In fact, the Bible IMPLORES people to learn about God and the faith, lest charlatans come and stray them from the flock. However, ALL THE WARS you mentioned were fought for economic and power reasons, not as a direct goal of the religion's theology. Because the masses are also a part of religion, and the masses will be manipulated by whatever that numbs their mind, religion has been used as a tool to control people. Religion, though, is not to blame, it is the people who manipulate it, and to a large extent the people who allow themselves to be led blindly. A shoe lace is used in a good way many times, but you could use it to strangle people. Is the shoe lace a murder weapon?
C. Again, if you KNEW anything about Christian theology, you'd know that the Catholics differ greatly from what the Bible actually says about salvation and the relationship we have with God. For example, in a a Catholic mass, the bread and wine is ACTUALLY supposed to BE the body and blood of Christ, not a symbol. Purgatory was introduced for a while, then phased out, but it made them a lot of money in candles and offerings. Heard of indulgences? Yeah, you could once buy your salvation. The Catholic Church has been corrupt since its inception. Read up.
D. You've probably heard of the "God Shaped hole" people have, an inherent sense of awe at the world and a feeling of insignificance that must be resolved by finding some sort of purpose and explanation for their lives lest they go mad? Answer me this? where does our conception of God, or even a "better" world, come from if we are the fabric of this Nature, an all encompassing system which somehow has allowed us to think beyond its very limits?
E. The only thing that will send (no, keep them on the path) people to hell according to Christianity is the failure to reestablish the connection severed with God. Not what they think about the entirety of the Bible, only the absolute fundamental doctrine of Jesus Christ's role in the grand scheme of salvation. Otherwise, millions of years, 7 days, it doesn't REALLY matter if this doesn't cause you to falter on the fundamental.
The Bible, and Christianity, has been the greatest agent of good in this world, and this since it's creation. Hospitals are a great thing, no? People still suck though.
F. The Bible, and Jesus, don't give you that option. He called himself the son of God, no other guru has ever done that. It means he's either batshit insane, or a liar and thus a bad man, or he was the son of God. He does not let you take his morals and stop. He, and the Bible, claim to have been the Truth. It either is or isn't. The Bible is not a code book for morality, it says to be the end all be all of how the world works.
Aut deus, aut hominem malus.
J. "Religious focus on blah blah blah" Oh come now, the Bible doesn't FOCUS on any of these things. The POLITICAL religious movement may, but not the Bible. There you go again, associating religion necessarily with anything that calls the cal on it. You can be upset, as I am, that the religious right makes it seem like Pslam 151 was written about gays, abortions and stem cell woes and then omitted. Now, explain to me why people in the western world, with a largely absent religious conscience, are still as prone to violence, rape, suicide and drug use? Haven't we evolved beyond the need for purpose dictated by religious institutions? Come on man, secular humanism has had its chance to show its obvious superiority to religious morals since they were outlawed in schools. I don't see anything much better, i'd say it got worse.
