A trip to the grave will solve the sin issue if repenting is not in the cards.
Job:14:14-17:
If a man die,
shall he live again?
all the days of my appointed time will I wait,
till my change come.
Thou shalt call,
and I will answer thee:
thou wilt have a desire to the work of thine hands.
For now thou numberest my steps:
dost thou not watch over my sin?
My transgression is sealed up in a bag,
and thou sewest up mine iniquity.
