It is Mirakuru, and yeah, he was insane. But he did kill millions of people in Star City. It is still seen as it's biggest attack and Freaking Ra's al ghul attacked it. I think the only reason Oliver is seeking his help is because of the team slowly being taken down like how Quentin was imprisoned in the trailer. Slade is being brought in as Oliver's last effort.
