4) Doesn't have the basic decency to ask if the dude is alright, and he justified this with an absolutely lame excuse (a common pattern with this dude) : he was afraid of going to see Battiston because French players were already there and "glancing at him menacingly"
There was an actual concern and a very bad atmosphere (understandably) at that moment in time. It's absolutely imaginable that Schumacher going over to the other team at that moment would have sparked something worse.
6) Makes fun of Battiston after the game, saying he'll pay for his dental. Oh, wait, no, years later he again lamely justified himself saying it just meant he was "relieved"
That is simply wrong. He said that if it was only his tooth that got knocked out (which is what reporters told him at the time) he would gladly pay for the dentist, because he was relieved that nothing worse has happened. Obviously spun the other way around because the narrative of him as the antichrist had already started to spread among French media.
He also personally visited him and apologized to his opponent in the aftermath.
It was a different time in football and it's a split second in the life of two people that had a big impact on them, both literal and in the other sense of the word.
His action in this moment on the pitch was more than just dangerous and clearly by far the most stupid thing he had done in his life up until that point but he was not a Pepe or Suarez who did these things before or ever did them again on a regular basis, usually even a somewhat calm and collected guy for a goalie. I know calling it a brain fart might sound like I am trying to play it down, but even a little moment of stupidity can have the harshest consequences which is what I think of this situation. Acting as if you knew all his intentions even though he himself stated otherwise on many occasions...well, that's what you can do, but you are not automatically right. He says that he came too late and I think he is not being totally honest at that moment. He was clearly intent on fouling him, he had been physical on that day before, probably trying to impress the French. I do not believe for a second though that he wanted to injure him as bad as he did, he is simply not that kind of person. Does that mean he is excused? Not for me, but he is also not the worst person to ever wear a football kit. He was a young man in one of the if not the most important games in his life who totally lost his head. He just should have been punished accordingly and that this did not happen is the actual problem. It's good that we live in a time where an action like this would never go unpunished (hopefully, although some people have brought up the Neuer incident vs Argentina as an example even though he actually got the ball and was clearly trying to get it but it's still an intersting question as to what a goalie is allowed to do). His (Schumachers) treatment by the French press was still disgusting though, if you want some examples I'll provide, not gladly though.
And btw if you want any source on the atmosphere in the stadium comment: I was there with my father watching the first football game to ever end in penalties at a WC. He was shielding my view on the pitch after the collision because he thought Battiston was dying. Might sound a little insensitive but it was still an awesome experience all around, but I was too young to think much about it after he had left the pitch and being assured that he would be fine seemed only logical to me.
