So assuming we actually believe in God, and the He is all powerful and all knowing, and assuming you and I actually have free will, etc.
Then: God already knows you are feeling guilty. That you actually feel guilty means you have a conscience. The question is, what do you do next time? If you feel guilty but keep doing it, then it isn't improvement. It seems improbable that God would want you to be immobilized by guilt. Clearly, this is a lesson. The question is do any of us learn anything from it? Perhaps it is not you, but we who are supposed to learn.
Of course, if we are willing to accept the paragraph one assumptions, we have to admit God allows children to starve painfully until death, God creates ingenious viruses and genetic diseases to cause unique crippling deformity and agony before early deaths. God allows torture. God allowed Joseph Mengela to go free and never be punished for his crimes. God allows two children to be born sharing vital organs, knowing one will die, and forces us to choose which.
Dare we state God is good? Can we do this without a sense of the absurd, without humor, without compassion?
