I do not know the exact nature of the situation, but it really does not matter. I would suggest not doing step 4 without a sponsor's guidance. In answer to your question though, I would make sure the house cleaning is thorough, this is a program of honesty. Furthermore, step 8, "Made a list of all persons we had harmed, and became "willing" to make amends to them all." "Willing" is the arcane piece to that step. There will be situations where making an amend is just outside of the realm of possibility. This is where the sponsor becomes vital in assisting with amends and house cleaning. I have heard of 9th steps that landed people in the department of corrections. Watch "My Name is Earl", that's how to NOT do a 9th step, lol. Hope this has been helpful.
