People need to get in the gym, get out in nature, get some stress balls or do something to get that pent-up aggression out in a healthy manner. If you are that angry AT ANY POINT AT A CHILD, especially YOUR CHILD, you should probably reassess the other areas of your life because something is lacking somewhere to be that angry at a defenseless (and sometime senseless) little kid. They have every right to resent someone who inflicts physical pain to their bodies.
