What is exactly "to sin"??

For religious people that is a tough one, because they are often afraid of doing anything wrong, they will be "punished" later on.

We all do mistakes, don´t we? I guess we are here to DO mistakes and learn by them.

Is a mistake a sin? No.
So what is a sin then? Is it crimes? Is it sects with black magic?
Is it to think of forbidden fruit?

How do you define a sin?

Sin is a religious term, so for me is used more as a passing comment usually said in jest to my religious friends.

However wiki says it's: a term used mainly in a religious context to describe an act that violates a moral rule, or the state of having committed such a violation. Commonly, the moral code of conduct is decreed by a divine entity, i.e. Divine law.

Here they are, the 10 commandments....in every church there are paintings of God, heaven and so on, do the church failure on commands themselves LOL.

1. "I am the LORD your God who brought you out of the land of Egypt, from the house of slavery. You shall have no other gods before Me..."

This commandment is to believe in the existence of God and His influence on events in the world [24], and that the goal of the redemption from Egypt was to become His servants (Rashi). It prohibits belief in or worship of any additional deities.

2. "Do not make an image or any likeness of what is in the heavens above..."

This prohibits the construction or fashioning of "idols" in the likeness of created things (beasts, fish, birds, people) and worshipping them.

3. "Do not swear falsely by the name of the LORD..."

This commandment is to never take the name of God in a vain, pointless or insincere oath.[25]

4. "Remember [zachor] the Sabbath day and keep it holy" (the version in Deuteronomy reads shamor, "observe")

The seventh day of the week is termed Shabbat and is holy, just as God ceased creative activity during Creation. The aspect of zachor is performed by declaring the greatness of the day (kiddush), by having three festive meals, and by engaging in Torah study and pleasurable activities. The aspect of shamor is performed by abstaining from productive activity (39 melachot) on the Shabbat.

5. "Honour your father and your mother..."

The obligation to honour one's parents is an obligation that one owes to God and fulfills this obligation through one's actions towards one's parents.

6. "Do not murder"

Murdering a human being is a capital sin.[26]

7. "Do not commit adultery."

Adultery is defined as sexual intercourse between a man and a married woman who is not his wife.[25]

8. "Do not steal."

According to Rashi, this is not understood as stealing in the conventional sense, since theft of property is forbidden elsewhere and is not a capital offense. In this context it is to be taken as "do not kidnap."[25]

9. "Do not bear false witness against your neighbour"

One must not bear false witness in a court of law or other proceeding.

10. "Do not covet your neighbour's wife"

One is forbidden to desire and plan how one may obtain that which God has given to another. Maimonides makes a distinction in codifying the laws between the instruction given here in Exodus (You shall not covet) and that given in Deuteronomy (You shall not desire), according to which one does not violate the Exodus commandment unless there is a physical action associated with the desire, even if this is legally purchasing an envied object.

where is torture, child abuse, where is drug dealings, and the rest of the all bad things here on earth?

In which command do they fit?

in the seven sins ?

To sinn means to commit an error, to miss the target. Nothing to feel guilty as religions want us to feel for that way control the peoples minds by fear.

what do you mean by that?

I have errors with my computer, have I sinned then?

To sin is to revolt against God primarily. Sinners will face the wrath of the One True God. Sinners should feel guilty because they really are guilty.

Why should a person feel guilty by 'sinning'.

If a sin is to break the commandments or indulged in the (catholic) 7 deadly sins, why feel guilty?

Commandments: if a mother and/or father are abusive toward their child, how is that child supposed to honour their parents? If that child reported them to the police and had them arrested, are the dishonouring them? If that child defends themselves, isn't that dishonouring them also?

If a person was starving, and no one offered food...is it a sin to steal in order to survive?

Adultery: it seems to only define one instance...what about the other?

With the 7 sins, is it so bad for a person to experience lust?
Is envy such a bad thing? I mean envy could lead to someone working hard towards something.

So I wonder, if sin is a part of our lives; do we feel guilty? are we worried about the consequences when we 'sin'.
And given the above examples; are there loopholes into what is a sin or not?
