Is there any sin which does not have a negative effect on someone else?

no, there is no such thing as an individual sin. Just like a smile can make another person smile and etc. there's always a negative effect to a sin to another person.

No.

Really can't say I do. But sin is sin, big or small. If you commit it and feel bad about it even if it don't affect another then it must be wrong.

You mean human flaws and imperfections?

Sin is the concept of doing bad things.

It usually involves others but there are some exceptions.

Like the tried and true standard:

Denial of the Lord is a sin.

According to Religious Nut Cases and the Bible.

Morality has no need of Commandments or Supernatural Overlords.

Jelousy? only the person who is jelous is involved... there is really no victim

No, the sins of the father will be visited on the children unto the fourth generation.

The first thing that someone should be considering is whether the idea of sin is actually real.

If God is supposed to be perfect how could She have made anything or anyone that wasn't perfect.

Think about it. The idea of sin assumes certain things about God that seem highly unlikely.

First it assumes a God who is too incompetent to organize a simple educational field excursion and figure out a way to get all of the students home safely.

How likely is this that God would not be smart enough to come up with a plan for our salvation that is going to work 100 percent of the time?

It also assumes that God must have created us imperfect if we are sinners.

One might assume that God would be able to create someone perfect each and every time if he chose to. Assuming God is capable of this, then it follows logically that we must be perfect creations if we are actually creations of this perfect God.

Unless of course you are saying that God chose to create us imperfect.

If God created us imperfect then anything that may go wrong is Gods fault, not ours. This seems a bit illogical at best so I think that we need to assume that What God creates would have to be perfect.

If this is the case and Gods creations are perfect, then nothing that we can do could change what God created perfect and make it imperfect unless we think that we are more powerful than God is.

How likely is it that we the creation could be more powerful than the creator. I personally find this idea somewhat amusing, and a bit absurd.

Religion tells us that God is perfect. If this is true then it could hardly be logically for Gods creations to be considered to be anything less than perfect.

If this is the case and we are perfect creations of a perfect God then Nothing that we can ever do could possibly change this perfection that God willed, unless we were so powerful that our choices could override and change the will of God.

How likely is that????

Think about it.

You are putting the cart before the horse. It is the action that determines what is harmful in any given situation. There is no such thing as a "sin" just sitting out there.

If I steal a carrot to feed a starving child, this is hardly a sin, but if I steal the carrot from the child, it might be.

Lust and gluttony, for starters.
