All you need to do is read his interviews. He props himself up so much, which is important to do as an athlete as any sport psychologist would say. There is no point in competing if you don't think you can do well. But if he can't back up what he says about himself, then that talking is pointless and just points to a sense of hubris. He is especially known to blame his partner for his mistakes, which just doesn't fly with most people seeing as many in the recent past are his own. It's fine to make mistakes, but you need to accept them as your own and move on. You can't get better if you think you're faultless.
A perfect example of backing up the talk, is in your username. Plushenko is cocky and arrogant, but he
backs up what he says by performing well.
I agree we don't know about his true intentions, but his interviews say a lot about his personality. And believe me, I LOVED I/K. Katsalapov rightly has a huge ego because his skating skills are amazing. Ilinykh has that drive and x factor you can't teach. He was/is cocky, but with Elena it worked perfectly because she didn't need anyone to sell her because she's that incredible. If they stayed together, they could have easily dominated this entire quad.
But there is no point in thinking of 'what-ifs'.
