He also forced himself on Cersei at the side of their dead son (laid out for funeral).I really like Jamie too, &, if you think about it, the only truly horrid thing he's done is push Bran out the window. But pushing Bran out the window led to him becoming the Raven, which is his destiny. And, if you decide that everything is pre-ordained, then Jamie only "helped" hasten Bran along to his destiny.
He's the Kingslayer... and he killed the mad king when the king got way out of control. I hope he's the one that kills Cersei for the same reason.
