If we pray for Satan, and he repents, then there will be no evil because Satan is with God.
Satan will never repent, the Bible tells us so. You need to read the Bible more.
Satan's nature is malicious. His efforts in opposing God, His people, and His truth are tireless
Job 1:7; 2:2; Matt 13:28. He is always opposed to man's best interests
1 Chron 21:1; Zech 3:1-2. Through his role in introducing sin into the human family (Gen 3), Satan has gained the power of death-a power which Christ has broken through His crucifixion and resurrection
Heb 2:14-15.
Satan is destined to fail in his continuing rebellion against God. His final defeat is predicted in the New Testament
Luke 10:18; John 12:31; Rev 12:9; 20:10. The death of Christ on the cross is the basis for Satan's final defeat
Heb 2:14-15; 1 Peter 3:18,22. This event was the grand climax to a sinless life during which Jesus triumphed over the enemy repeatedly
Matt 4:1-11; Luke 4:1-13.
The final time............
Revelation 20:10 Then the devil who had led them astray [deceiving and seducing them] was hurled into the fiery lake of burning brimstone, where the beast and false prophet were; and they will be tormented day and night forever and ever (through the ages of the ages).
