Justifiable Suicide?

I read an article in the NYTimes about suicide and suicide attempts by women in Afghanistan. By fire.

Cooking oil and matches are readily available. Girls are all but sold to much older husbands who rape them, beat them, and shame them. Their families--if they are still allowed to see them--can offer no protection. These women and girls have nowhere to turn. So they choose suicide by fire.

One woman's husband taunted her that she did not have the strength to burn herself. Unfortunately, she did.

I don't know that suicide is ever justifiable or warranted, but I think I can understand, maybe a little, what would make one of these woman choose such an escape.

What depth of pain must my brother have been in? He had a family that loved him, friends who cared about him, and so many people who would have moved heaven and earth to help him. How could he have seen suicide as the only way out?
