We are not saved by feelings of sorrow over Jesus' death. We are saved when the Word of God 'pierces' our hearts (Hebrews 4:12), when we are convicted of our sins and trust Christ by faith.
We will pray that God take the lives of these Hitler-like men from the face of the earth.
Satan is the ruler of humanity (John 14:30). The result is that lost mankind hates and rejects Jesus Christ:... And, since unconverted mankind hates Christ, it also hates those who love Him and follow Him.
