I guess you need to ask yourself:
"Are you trying to justify something that is wrong or do you really know for sure that what you are doing is right by God's standard?"
It's between you, God and the Holy Spirit. You already know the answer. It's just possible that you don't like the answer.
From my personal experience, there have been too many times that I have tried to justify something that I thought was ok but ended up only hurting my relationship with God.
