Guess he didn't hit anything vital.
I have a lot of sympathy for this man.
My mother cried out in agony as she was dying from cancer and we could do nothing. One has to experience such a horror before judging others.
The story gives us no facts other than he shot and killed his wife and tried to kill himself. Who knows what type of suffering she was enduring. Maybe she asked him to take her life. I don't think if she did, that's his prerogative, but maybe it can help us understand if that was the case
A lot of unknowns are left unanswered.
Anyone who has endured serious long term pain and suffering easily gets despaired and a sense of hopelessness.
