The biggest sin

I don't really pay attention to biblical stuff, but I think the worst thing a person could do is to torture/torment others. I think it's absolutely terrible for someone to put other people in emotional or physical pain.

Sans the 10 commandments, I believe the worst thing you can do is take a human life. I know that there an instances where someone killed for self-defense, maybe we can rule that out, but still, for me, killing someone is the worst you can do; a life can never be brought back, unlike if someone is robbed of material things, it can easily be replaced.

1. Having Other Gods or idols - idolatry i think is the first biggest, we should not have other God before him, the ALmighty... if not, it wouldn't have been the first commandment of God... i guess. and then second for me is Killing someone - taking life of course is a sin, we do not have the right to take a man's life... worse torturing that someone... we are humans and must act like one, not animals. We should love and be considerate of each other.

I don't think any one commandment is more important than the others because when God sent them to Moses on the mountain, he didn't say they were in order of importance, just that these were the ten commandments. I take them all very seriously.
