Hyprocrites & Truth

There's some things in life that I'll never fully understand.For example, Christians who live their life through the Bible and critisize and guide others through words in the Bible but when they think nobody is watching - they let their guard down. The Bible isn't a thing to "half follow". People pick and choose what they want to believe and what they want to participate in. I've seen people argue against homosexuality, saying it is immoral and a sin, and that everybody who is homosexual should go die. They say that they are Christians to the core. Isn't that slightly contradictory?
I don't believe God has "rankings" for sins (i.e. adultry is worse than lying, etc). So, how can people with Christian beliefs wish somebody to die? I've seen it way too many times, not the exact situation, but the general concept, and it just confuses me beyond words. Given, I'm not a perfect Christian but I'm trying to grow in my relationship with the Lord and live up to what He wants for my life. However, it seems like common sense not to say a sin is wrong, then go right on and do a sin yourself, all in the same sentance. Especially one that is so blatant and out in the open.
I've started wondering what God thinks of these people. I don't mean "thinks" but that's the best word I could come up with at the moment. Is He showing them subtly the error of this thinking? Maybe I'M the one that's wrong in this, we can't know. But, if I'm right that this is hypocritical, will these people ever see the fault in their thinking process?
Which also makes me wonder about something not revelant to hypocrasy. Does God reveal to people the truth of things? If a situation is present and a person causes pain and hurt (emotional or physical) because of what they believe on the topic, does God show them the truth? It's recently happened to me. I was cursed at and told I was a waste of time, because a friend believed a lie she heard about me. I said I hoped God would shed light on the issue, and show her her thinking was incorrect. But, will this happen? Does God let us mentally fight battles so we can realize that the only truth we can find is in Him? Or does He show us the way, obviously or subtly, to guide us in the right direction?
Hm. I'm not sure. It's a hard issue to wrestle with.
