Those are right motives, but that is not Biblical holiness, which goes beyond natural consequences as motivation, and even despite them, for it is ultimately driven by his relationship to God and what His will is. Joseph's response to a women who wanted his body was,
"There is none greater in this house than I; neither hath he kept back any thing from me but thee, because thou art his wife: how then can I do this great wickedness, and sin against God?" (Genesis 39:9)
Even if, like a king's son, one can commit sins without suffering earthly consequences, yet their is that which is eternal:
By faith Moses, when he was come to years, refused to be called the son of Pharaoh’s daughter; Choosing rather to suffer affliction with the people of God, than to enjoy the pleasures of sin for a season; Esteeming the reproach of Christ greater riches than the treasures in Egypt: for he had respect unto the recompence of the reward. (Hebrews 11:24-26)
And ultimately the purest motive to live holy is not one affected by fear of negative consequences, but of love for God,
There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love. (1 John 4:18)
Out of which we should be willing to go to Hell if that would give God glory, which the giving omniscient omnipotent God does not need, (Acts 17:25) but which is only right and what is best for man to seek to live for.
I understand that there is an ideal standard, which is the biblical one. But nobody on earth starts out with the Biblical standard when they accept Christ.
It’s all a process towards the ideal. As you study and learn to pull back, you’ll make these considerations along the way until you might reach the standard one day.
God did that with the Israelites. He expected obedience, without explaining why they should obey and they eventually figured out that obedience leads to mindset and heart changes.
