Yes, it was ultimately right that these men were drafted against their cultural standing to burn Ebola infected bodies. The medical officials where this took place felt that the burning of these bodies would ultimately result in less people getting infected and dying. This is more important than cultural pride.
Even though the men who were drafted to burn the Ebola infected bodies were shunned by their community, they saved the lives of many. They are still alive and fine and they solved what could have been a world wide epidemic. Even though cremation is taboo in their country they saved the lives of many. I'm sure it was difficult but it helped overall
It is a horrible task to do but somebody's got to do it. However that doesn't mean you simply force people who don't want to do it. There are stories of people finding the body they need to burn and seeing that they recognise the name and they known the person. That is harrowing. It should have been medical experts from other countries doing this task.
There are some things that no human should be forced to do. Burning a body is one of them. Killing someone is another thing. Dealing with medically dangerous situations is also a problem. If they pay enough money, there are always people who are willing to do the job. They should find volunteers.
