Kon got messed up originally when Johns got a hold of him. He was bad all the way up until his death and return, where at least some attempt was made to fix him, but this came near the end of the pre-FP era anyway so it didn't last long. The New 52 concept started out great. Lobdell was actually setting up some great things. Had he kept things simple, it could have ended up his best work in a long time. ..then the stupid Harvest stuff happened. Then DeFalco happened. Then the coup de grace was the reveal of his official, totally convoluted origin.
