Turn 1 was fueled by a lot of politics, revenge, grid selection changes. I think it was a little more complex than "I am a whiny baby and if I can't win nobody can". It wasn't "right" and was the focus of much debate. Yes you found ONE instance where Senna may have had a moment of weakness. Schumacher made sure to show time and time again just how much of an ******* he was. Much like Hamilton does today.
