Well I've read it all on this forum now. She was a missionary. I personally know missionaries who do or did mission work in Mexico. They are all aware of the risks. One pair very reluctantly stopped regularly going to the Reynosa prison, mostly because the authorities there couldn't be counted on to let them enter, and it breaks their hearts they have had to stop.
The others regularly drive between the border and Monterrey area, doing their jobs, doing their mission work, serving the Lord.
None of them deserves to be called fools or damned.
They are doing the Lord's work, and I praise them for it. Everyone dies at some point. It is not stupid to die for a cause that you believe in. I have a good friend who is doing missionary work in the “Stans” those mostly Muslim countries that used to be part of the Soviet Union. He does it with his wife and a couple of babies. I am amazed at the stories that he tells.... I do not consider him a fool, but he is a true believer.
