Basically none of this can be proven, since it's all hypothetical, but here we go.
Consider:
Cloning humans is against ethics.
Testing experimental disease treatments on humans is against ethics.
If we cloned humans and tested disease treatments on them, cures for many diseases could be found and implemented.
As a result of these cures or treatments, more lives could be saved than those lost by the clones.
I am not in any way suggesting we should clone people and give them diseases so we can test cures on them, but here is my point. Usually ethics tries to center on the greater good, right? But in this scenario the greater good is immoral. Talk about it.
