Jesus said in Matthew 5:44- "But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you and pursecute you."
Satan is a beautifull creature of God just like every person. Sin has destroyed Satan and it has destroyed us. God made us all for a purpose. I purpose is to love not to hate. The more we hate the worse things will become. Hating Satan does not bring you closer to God. As long as people hate Satan, Satan will keep growing angrier and angrier. LEAVE SATAN OUT OF IT! People should know about Satan but it was what he did that was wrong- he is not completely evil. Satan has done things that were wrong. So have all of us. Focus on what Satan did that was wrong. learn from Satan but have compassion on Satan. Have mercy on Satan.
2 Peter 3:9- "The Lord is not slack concerning his promise, as some men count slackness; but is longsuffering to us-ward, not willing that any should perish but that ALL should come to repentance."
God is not willing that any of his sheep be lost. Satan included. Jesus was crucified because people did not understand the Bible. They did not understand how God works. People thought that the Messiah would be an earthly ruler who would establish a kingdom through war and conquest. People could not understand why Jesus would love "sinners" and God thinks the same as Jesus. Just as Jesus was so much more loving than people expected- so is God. People though that Jesus was blaspheming the scripture instead of fulfilling it. People do not understand the strength of God's love. God's love can conquer all evil in every heart and mind- even that of Satan God does not want Satan to perish so God will make a way for Satan to escape corruption.
