An acknowledgement of wrong done and wanting to make things right isn't weakness, it takes strength of character to do that. And when that is done, our concsience in relationship to God or relationship to others whom we had wronged is clear. Only then can we live life to the full without remorse and guilt holding us back. Taking punishment because we aren't willing to accept responsibility for wrong done is stupid. 1 John 1:9 in the Bible says, "If we confess our sin, God is faithful and just to forgive our sin and to cleanse us from all unrighteousness."
