Then right and wrong is an individual decision? In which case it explains how people can murder without conscience? Seems to me it is a function of basic humanity, be it conscience, religious beliefs or just DNA ... a code of morality exists in everyone .. when it doesn't you have the greed, the murder ... and hence more laws to fill the hole that was left by the lack thereof

So abandon anything that expresses any morality?   seems to me that is a mistake also ... but that is just my opinion
