Okay, I see what you mean now.
I don't think there was sin or evil in the world before Adam and Eve chose to introduce sin in the world through the serpent's influence. I say "I don't think so" because the bible doesn't expressly say there was no sin or evil. Instead, it says, "God saw all that he had made, and it was very good." This is probably a good assumption. But you asked about heaven, not earth.
I guess I've always just assumed there is no sin or evil in heaven. I think this too is a pretty good assumption on my part. I don't think God tolerates sin. But I'm not sure the bible expressly tells us that there is no sin or evil in heaven.
