We are born sinners. Everyone is 100% responsible for his own sins; blaming others won't get you off the hook. Of course, if your sin causes others to sin also, then it becomes doubly serious. Anyway, since God hates only the sin and not the sinner, you should do so likewise. Therefore, do not debase yourself after you have sinned, but realize that you have offended the Lord and ask him for forgiveness, and he'll make you pristine again.
