Noir you points about "religion" characterizing people as weak, sick and sinful needing help is somewhat correct.
The question is whether it's true or false. You seem to say you don't like it. heck I don't like it, but it doesn't mean it's not true.
You say lust is really not bad "unless it goes to far"
greed is really not bad "unless it goes to far"
and MOST people don't go to far.
Can you say that there are very many people that in your view at one time or another have gone too far is some moral issue.
Have you done things that's you've genuinely should have apologize for, because you've done it out of selfish anger? Have you stolen anything?
I'm not trying to guilt you, seriously. it's just that most people will admit that they have not lived everyday full of love and righteousness. Or even lived up our own skewed personal standards of right and wrong.
Even our own conscious's tells just we're wrong. Without having much in the way of "religious" teaching.
Something is set in us as little children that says "that's not fair", "that's not right", "that's not nice" "i'm sorry".
Why aren't we "fair" because we are NOT weak?
why aren't we "right" because we are NOT sick?
Why aren't we "nice" because we are NOT sinners?
you may not like "religions" codification of morals and plain speak about right and wrong but you can't honestly say that people are naturally always good, kind and moral by default. i think we all know that religious and Non religious people COULD be better. And it would be GREAT if we all lived up to what we know is right and good. But we don't. So we have contracts and laws and locked doors on our houses and cars and bikes, politicians lie, companies lie, preachers cheat on their wives, moral atheist cheat on their wives, people cheat from their jobs, kids steal money from grandma, Neighbors play music much louder than they know their neighbors want to hear, we fight animals for sport, we excuse/justify our faults and demand blood from others for theirs, we pass by people in need everyday and don't help, and often don't even grant small acts of kindness to others etc etc etc
I could list plenty more, so i'd say the fact that we do not live up to what we all know is right and good is proof of our weakness.
If we go farther than most that it shows we are morally sick.
Either or shows we are sinners.
But maybe your the 2nd exception.
