Guilt is anger directed at ourselves--at what we did or did not do.
Peter McWilliams,

In my opinion, guilt is a sign that something might be wrong, but not necessarily anything you did. The point of the feeling is to stop and examine the event in question more closely and determine to your own satisfaction, perhaps by checking with the other persons involved, when applicable, whether you are truly at fault or to blame for something you did. If yes, then take appropriate action to fix the problem, for example with a sincere apology or restitution. If no, then let it go.

My point of view, I witness so many expressions of anger that have been directed towards the wrong people and we have been guilty ourselves of this infraction. For example, let’s suppose that you suspect your neighbor has stolen your garbage cans (excuse the pun, but this situations stinks!). Instead of asking the neighbor or attempting to resolve the situation with him or her, you come home upset and yell at your children out of anger. In this case, the proper object of your anger should be your neighbor, but your children became the object of your anger instead.

I think, PETER McWILLIAMS expresses to anger would bode well for us and, as a whole, for society. All too often what is witnessed nowadays is anger directed with no aim or purpose but simply for the sake of getting angry. The objects of anger are aplenty but the proper objects are scarce. It seems that many people are not deliberate enough about the anger expressed and this can produce grave consequences. Moreover, it is important to remember that this problem involves everyone. Although not everyone struggles with uncontrollable anger, all of us have been affected by it either as the guilty party and/or as the victim.
