I think if you really put things into perspective, you'd see that good is way more powerful than evil. We can see this by example of our God rising from the dead.
The Jewish leaders hated him, and the Romans carried out his execution.
After the mocking, flogging, abuse, thorns, blood loss, and piercing with a spear, came his burial.
What more could they do? They killed him. They took his life. He DIED!
The next thing they knew, he walked amongst them again! I could not imagine how creepy and scared they'd be running away. Thus the hymn is sung "Let God arise, let his enemies be scattered! Let those who hate him flee from before his face!" Can you imagine!
After all their horrors, their evil, his goodness was more powerful.
