Kindred,
All you have to answer is, "Would you like something like this to happen to you?"
To begin to understand the gravity of breaking the Lord's second Commandment, simply answer the above question and how much would you like for this to not happen to you.
That is how you know when something is a sin and how grave a sin might be.
Never assume you will be forgiven by the Lord, because you never really know until Judgement Day.
The best course of action is that if you think you have sinned, confess, repent and atone fully your crimes against humanity, the victim(s) and the Lord ( for disobeying the Lord's Commandments).
