Who was more evil The MCP or CLU?

Who do you all think was more evil? The Master Control program? Or was it CLU. The MCP was ruthless and said he was better than humans when he was talking to Dillinger. But in the end CLU also wanted to being his army to earth through the portal and try to rule over humans or so it seems. The story was always something about programs or machines getting to smart and taking over humans. Also how humans could go into the world of the computers and fight against evil forces like CLU and the MCP. Overall it's hard to understand the story. But Who do all you programs think was the most evi? Was it the MCP? Or was it CLU from Tron Legacy. We know it can't be CLU from the first Tron because he fought for the users! Well let me know what you think programs just a thought before bed! See you on the grid!
