Wrong. He was using the rules towards his teams advantage, everything he did was by the book - addressed by the rules. The rules state - if you deliberately handle the ball on a goal scoring opportunity, the penalty is a send off and free direct kick or a PK. Those are the rules. He played by them. The penalty for kicking a ball out of bounds is either a goal kick, a corner, or a throw in. Defenders kick the ball out of bounds to prevent goals all the time. A handball outside the box is a direct free kick, inside, it's a pk, nobody would call him a cheater if it happened outside the box at midfield, no one would question his integrity if he had intentionally fouled a player about to score. It's a transaction, a part of the game, nothing more, nothing less. There is no moral value associated with this.
If you have a problem with this play, then you have a problem with the rules, not the player.... back to square one - don't hate the player, hate the game.
