I've always been of the opinion that I shouldn't judge without hearing both sides of the story. Perhaps that's my training. When people are no longer living to tell their side of the story, I believe its always unfair to judge them without evidence. Taking one's own life is not an admission of guilt. It's often a spontaneous act to end an emotionally painful situation.
No one is accusing the husband of anything. We're just refraining, in the absence of evidence, to judge someone who is no longer here to defend themselves. It's a moral and ethical choice that I always make in these situations, particularly where suicide is concerned.
Many people in our society still don't have a healthy grasp of suicide, what causes it and why its important not to judge those who resort to it. It's a bias that harms not just the deceased person, but everyone who loved them. Something to think about. JMO
