What is the ruling on working to develop software for a funeral arrangement company that undertakes washing and burial or cremation, and other services?

"Programs that can be used for both permissible and forbidden purposes are not problematic to work on and develop, as long as their use in the forbidden does not become predominant. This program can be used for permissible services, such as burying the deceased and deleting their accounts, and forbidden ones, such as cremating bodies. As long as most of its services are permissible and its use in the forbidden is not exclusive, there is no harm in working on its development."
