Bahrain - You cant say that Vettel wouldnt have won, Alonso was only 2 seconds behind and slowly catching when he got the problem, so there is no guarantee that he would have won.
Vettel was comfortably leading, having been faster all race, as he tends to do; just be out far enough in front and bring it home. Not many will agree with you that Vettel would not have won if not for the spark plug.
Malaysia - Does Alonso'e engine blowing up from 8th Place on the last 2 laps not count as "Bad Luck".
My bad. I'll edit that
Europe - If hamilton got penalised like Alonso did in Silverstone, he would have been out of the points.
Hamilton got the exact same penalty; yes, it was bad luck he got stuck behind the safety car, but if he didn't provoke the penalty to start with, it would not have been a problem.
Germany - How Can you take 7 points off Alonso. He won the race.
He won the race illegitimately.
Korea - Again, if you watched that race, you would have seen how quick Alonso was when Vettel blew up. He was 4-5 seconds a lap faster than ANYONE thanks to him saving his tyres behind SV. So, no guarantee that Vettel would have won that either.
Like with Bahrain, it's a long shot to say Vettel would not have won this one: he was faster all race, in control, and only started losing to Alonso laps before his engine gave out.
The other point I want to make is that Ferrari and Red Bull obviously went for different tactics.
Red Bull went for Speed, Ferrari went for Reliability. So you can say "misfortune", but if the Red Bull was as reliable as the Ferrari, then it probably wouldnt have been as quick. It is not as straightforward as you try and make it.
Yes, there will always be a necessity for some people that there is a big disclaimer explaining things like this, but when the general consensus seemed to be 'we don't understand how Vettel took 'till the last race to win the title in the fastest car', this is the easiest way to put things into persective.
