I’m not sure what sort of harm you’re trying to achieve, but it depends on a lot of factors.  Do you want it to be permanent or temporary?  Do you care about the specific health effects, or just whether you get your desired results?  Do you need your attacker to survive and remain conscious so you can interrogate them?  Would you need to be able to prove that you caused the injury, or just want plausible deniability?

I’m not sure if we’re having a practical conversation about things you want to accomplish, or a philosophical discussion about values and right and wrong?
