Sometimes seeing decisions taken by VAR in our current football game is questionable.
If I'm the one in charge of the VAR to take decision of hand ball incident in football will be

1. When the ball hit an opponent hand in the penalty area or within the 18 yards area by taking an advantage to score, that particular goal should not be counted either accidentally or not

2. When the ball hit a defender hand in the penalty area without the hand been in it natural position" should directly be awarded as penalty but if the ball hit the body first before reflecting or hitting the hand should not be awarded as a penalty because that hand can never be in it natural position because anytime a ball hit a body and reflect or bounce back to hit the hand, that's particular hand has already been taken off from it natural position.

3. Since there is fair play in FIFA, assuming you are defending in your own half and all what you realize that your opponent has sent a powerful shot and it is coming directly into your face and you accidentally used your hand to save the ball from hitting your face, should never be counted as penalty if only by reviewing by the VAR to know that the time the defender saw the ball coming was unrealized and has no option to defend the face because one aim in of promoting football is through fair play.
