We all came from the loins of Adam and we were in Adam. No one is born innocent. God is infinitely Holy, he will not tolerate sin. When we sinned against the infinitely holy God, we deeply hurt God. The hurting party is the Father, as we violated his law by sinning.
Sin is the transgression of the law.
All unrighteousness is sin. Although God provides rain and sunshine upon the just and the unjust where sin is concerned God is not happy but angry. God is angry with the sinners everyday. Also the scripture is clear the unbelievers are hostile to God, not friendly. If there are two parties angry at each other, there is no peace between them.
