Perhaps an update is in order:
The guy apparently had already helped this kid get one ball, and gave this ball to another kid sitting by him.
ETA: I wonder what it’s like to be this poor guy and have an out of context and misleading clip of yourself going around the internet with people all over the world calling you an asshole and wishing bad things upon you, when not only didn’t you do anything wrong, but you were apparently a good guy according to the people actually there. That’s got to be a bummer.
