Amazing Landing as Wing Hit Runway

I can't believe my eyes when I saw this UK Sun report and video (longer and better video) and AP report and video of a Germany Lufthansa flight's (carrying 131 passengers) wing grazing the runway as it attempted to land amid gusting wind. They were so lucky.

Many people and news media are calling the pilot "hero" as the plane's wing grazed the runway and almost crashed.

Now, I do have question about the first and second landings. Note that I am not a trained pilot and it is probably unfair to second-guess the pilot without full details of the conditions at the time. So I might be quite wrong in the following.

With respect to the first landing, I wander was the plane already blown off course before it got dangerously close to the ground? As the plane looked quite unstable and wobbly based on the poorly angled video. If the wind condition was that bad, maybe a more experienced pilot would have abort the landing earlier and execute a missed approach (see this FAA Decision Makers Guide or other similar international equivalent guide) instead of trying to land the plane? (note 1)

With respect to the second landing, was the pilot worried about the structural integrity of the wing after it grazed the runway and wanted to get the plane on the ground as soon as possible? If thats not the case and since the runway was still in poor condition to land, I wander if the polit has thought about flying to the destination alternate aerodrome (alternate airport) for safety reason? Standard operating procedure should have allowed for enough fuel on the plane to fly to the alternate and not risk the passengers' lives in trying to land in unsafe condition.

note 1: Have you ever wondered why when a plane lands, it always seem to be at maximum power? Well, the reason is just in case the plane can't land and have to execute a missed approach and to fly up again. And to do that, the engine has to be at maximum power, capable of taking off and fly around. Something I remember from a Air Traffic Control training course years ago.
