I think you're massively over egging this because you blame him for Labor's woes when there's plenty of blame to go around for all for that debacle.
No, there's not. Rudd single handedly ruined Gillard's government out of spite. All parties have issues, Rudd took them to a new level, leaking things to the media when she was doing well in polls. Essentially spent 3 years actively ruining her government, and she was still able to accomplish alot.
In time she'll be remembered as an incredible leader.
I hate Kevin Rudd, he's an awful human being. I'm rapt Turnball didn't give him the job and I'll be happy if i never have to hear about him again. He shouldn't be given any job of any importance. The media, all political parties etc should shun him. He's proven time and time again that he's a despicable and untrustworthy person.
