I do like that one about treating others as you would like to be treated yourself.
Sure there are indeed valuable socialized concepts which are still useful and beneficial for mankind, the basic tenets of Christianity are just that.
But before those were established there were the ancient Hebrew socialized laws of behavior which many were simply not , such as ......
Children who dishonor their parents should be put to death.
Children should be punished by striking them with a rod or stick.
A rapist against an unwed girl can buy or pay a dowry to the parents of the girl and marry her even if she does not want to.
Serious hurtful crimes against people can be dismissed without paying a penalty if the said perpetrator does not admit to the accused action and there were not two witnesses to the event.
The list goes on and on.
