Because we misuse our wills, all people are evil. But no person who possesses and uses his will is free from evil. Therefore, all people have guilt. Therein lies God's basic problem in His association with people. God is totally free from all evil.
All people have evil.
Because people are evil, they have guilt. In that act, God made Jesus to be sin. Every person who will trust and accept what God did in Jesus as he died is forgiven. Forgiveness provided through Jesus' blood literally destroys the sin. By destroying the sin, God destroys the guilt.
