Not quite, he's also losing everybody else in the future he could have saved, but won't (because he's now dead).

The point also, was that when you do such heroic acts you force others into danger into saving you. It might be your intention to die honorably, but they'll come to your rescue anyway because you ran out like that. That was his point here.

The exam didn't quite make sense. Did Deku have to come last in every test to fail? Or does he just have to come last overall (even though there's no % grading)? He beat Nice Person in the sprint already, so he certainly wasn't going to come last in everything.
