In your opinion, what's the worst sin to possibly commit?

Well I have indeed committed many minor sins ..But for me cheating a girl after having physical relations (of course without protective measures )with her would possibly be the worst ever sin committed by anyone . Its hard to even imagine and persons who commit that kind of sin should be hung if you ask me !

I think cheating is the worst sin to possibly commit. It tarnishes relationships. It destroys trust. It destroys families. It can even kill a person - kills the zest of the person's life. It is brutal enough to make the person being cheated to not recover quickly. Some don't recover at all. People who cheat should realize that it's not easy to be cheated on. They should understand that their actions has just broken someone and that someone could never really recover completely.

For me, the worst sin to possibly committed is not respect to our parents. It seemly become a trend for this century where most of the teenagers are less in respecting their parents and sometimes will throw out some bad words in argued with their family.

yes .. you rigth all sin is the same way even you not religion for it coz is has been put in in fist time with PROPHET ADAM , HE GET BANISH FROM HAVEN

Yes, all sins are equal. Once its committed you have to repent it sooner or later. Since a sin is at once a rebellion against the omnipotent creator risking punishment (even hell). A robust finding from social science research is the most people think they are better than others; more ethical, considerate, industrious, cooperative, fair, and loyal.

thou shall not lie... lying may be the root or cause of all other sins....
