Those engineers are the one facing the court, as they failed to obey the requirements posed upon them by the legal system when they did their oath for professional title, and signing their name on the project.

The value of human life in most places is exceedingly low. In the US if a company kills ya due to an OSHA violation the company pays something like 35,000 to OSHA. I imagine that's more than a Congolese cobalt miner, but when you compare it to the cost of say a car, a house, an education, etc. It's pretty sad out there.
