They are sins. They are addressed in 2 of the 10 commandments. Everytime we commit a sin we pull ourselves away from the love of God and something always dies. The wages of sin is death. Something always dies when we sin.
Adultery leads to the death of our relationships within our family.
Lying leads to the death of our ability to hear and understand the Truth, and the death of trust within our community. The whole situation sounds like a terrible, sordid mess to me. But, it is still under investigation, so it is not appropriate to say much more than I've just said until the whole story slowly comes out. The only thing I can compare this situation to in scripture is the David and Bathsheba affair. Look it up yourself in II Samuel 11.
