At thy right hand there are pleasures for evermore (Ps. 16: 11)
A man of great wrath shall suffer punishment: For if thou deliver him, yet thou must do it again.
Proverbs 19:19
We have two important principles established in this brief proverb.
The first principle is that you cannot have sin without consequences, and you cannot have great sin without great consequences. If a man is a volcano, it is useless for him to complain about all the cooled lava down the sides.
And the problem with angry men is that they focus on all the irritations that others provide for them. That is their default drive. And then, when they suffer the consequences of their own anger, they tend to attribute this to others as well. The recoil of their own actions is taken by them as some random third party slapping them in the face. They think the lava must have come from some other volcano.
This relates to the second principle taught here. If you help such a man, if you bail him out, if you help him pick up the pieces, he will almost certainly not take away the right message. The helper is thinking “I hope he sees how much I care, how much I am helping him. I trust that this will be the last time he will do that.” At the same time, the man with the temper is concluding that everyone seems to be taking things in stride, and that it must not be that serious. The person who delivers him from the consequences of his own folly is going to be called upon to do it again.
So the principle is this. You get more of what you subsidize, and less of what you penalize. In this case, the penalty can simply be allowing the angry man who pay the fines that he inflicted on himself. He will be tempted to blame others for these fines, for that is what angry people do, and the person who helps him pay those fines is reinforcing the misinterpretation.
