I'm writing a sci-fiction novel, it's centered around Virtual reality. The antagonist creates the VR device, so that disputes can be solved without bloodshed or war. But for doing that, he lets a few thousand people go to coma. The protagonist wants to stop the Antagonist to save his friends. Does this make for a good antagonist. I felt this would paint the characters in shades of grey, rather than separating them completely as good or bad. How interesting is this? Please do tell me.
