Unethical human experimentation

Unethical human experimentation is when scientists or doctors do experiments on people without permission or without caring about what harm those experiments could cause. It's wrong because it's not fair to the people who are being experimented on. They don't have a choice in what is being done to them and could be hurt either mentally or physically because of it. It's also wrong because it sets bad examples for other scientists and doctors who might be tempted to try unethical experiments just because someone else did it.
