Making a choice to protect people trying new treatments keeps those people safer but the trade-off is that you develop new treatments slower, which means more people suffer and die waiting for treatments.

Developing quickly versus safely are different decisions, but I don't think one is purely stronger or weaker than the other.

There is no doubt that China has weaker ethical rules compared to the West, but I think in this case, as long as the person consents, what's the problem?

Do you necessarily think that it's more ethical to have laws or rules that forbids suicides or self-harm regardless of what a person wants?
