Oi.
"Is a blood sacrifice required for every sin?"
Yes. Again, I don't have the program that lets me find verses easily, so if you can't take my word on it, sorry
"What I get from this, is that you could be an ass all your life, get re-born when you find out you have terminal cancer and get into heaven."
It's possible. How many Atheists find that they've lived their life in a way they don't like when they're faced with their own morality, and try and live the rest of their live the best way they can?
"So why would I or any decent person want to live with all of the pedophiles, murderers and general slime of society just because they repented at the last minute."
What you're feeling is vengeance, which is considered immoral by most human societies. If the person is no longer doing bad, what's the point of punishment? Forgiveness is a beautiful thing, you know, if the person has truly repented.
"Ah but as a catholic if you confess your sins your are again cleansed from sin so yes it is a free pass as long as ater you kill the person you go tell god about it and say sorry all is good."
I'm not Catholic, but from what I understand, even Catholics believe that you have to repent. Mouthing the words "I'm sorry" isn't enough.
"I understand the point of 'better life', but it appears the religion has allowed the 'belief in God' to be more important.
But there is no requirement to lead a better life. Just believe in god."
The institution requires that it has followers, that's the basic law of meta-evolution. An organized system requires that it lives and reproduces; the institutions that don't aren't the ones that linger for us to bitch about.
But True Christianity (tm) doesn't say you just have to believe in God. The devil believes in God, and that doesn't save him. In fact, Jesus had quite a bit to say on the matter (" But...Father, Father, I cast out demons in your name!" "Get away from me, I do not know who you are.")
"essentially anyone can apply by believing, no matter how they conduct themselves here on earth."
Yes, any person can apply, no matter how they acted, but salvation is a journey, not an emotionally-charged Wednesday night under a big tent.
"The reality is that these traits have evolved in us and kept by us for our survival, that much is clear. They aren't going away. "
Star Trek (a program with an Atheistic take on the future) shows how people learn to work as farmers to feed their brothers, not to be able to buy themselves a nice, new shiny car.
We are social creatures, but greed still perpetuates the machine of civilization. Can we evolve past that? Maybe, maybe not.
"I wanna know if Jesus died for the sins of people on other planets or if they have their own Jesus. "
Other creatures have their own laws. The angels will be judged by men, not Jesus. Humans have a unique (as far as we know) history, and set of rules. Maybe aliens never ate from the Tree, or they were never put in a garden to begin with. Who knows?
