You mean by calculation, right?

I mean, if every suicidal person saves the lives of up to eight people who want to live, it might be worth outright encouraging this approach, rather than having suicidal people kill themselves in ways that damage their bodies for this purpose, and then spend effort and money trying to bring them back.

Once a certain number of people is reached, though, there might be a degree of overabundance of organs compared to the needs, and unless you want to make the jurisdiction that allows this some sort of exporter of literal human resources, you should probably stop there.
