There's something you're forgetting- because of this man's foolish pride, his children are now without a father. He could have easily gouged his faithless wife in both custody and financial arrangements. Now his children are either left with a mother who is a lousy role model or they wind up in someone else's custody. That's too high a price for blowing away some hormone-crazed kid.
"He could have easily gouged his faithless wife in both custody and financial arrangements."
I wouldn't bet a cent on that. Besides, then the adulterous little punk gets off scot-free.
We are not talking about pride, here. We are talking about blinding rage resulting from some punk sniffing around where he had no business and ruining this guy's life. Can you even fathom that? No repercussions for ruining the lives of a whole family.
If I pinch a girl on the butt, I can be arrested for sexual assault. I sleep with some guy's wife, ruin his life, her life and their kids lives and nobody can do a thing to me.
That rage and the feeling of helplessness and the knowledge that nobody can do anything to the punk for ruining lives will often lead to violence through crimes of passion.
I could not condemn a man for shooting me for sleeping with his wife.
