Borg medical practice

[Isilkor]

But then how far could you go? Would you remove a humans limb and replace it with a robotic if he requested it, as you could potentially see it as benefit in the long run due to having a stronger limb? That I'm not too sure of.

I believe that administering a treatment is not harm as long as it is medically indicated. I.e. injecting atropine in somebody who has been hit with sarin, or using pentetic acid as an anti-rad/anti-tox treatment. Both of these cause minute amounts of "harm" in the literal sense, but alleviate far bigger problems that the patient may have. Similarly, doing surgery to remove staples, shrapnel or bullets would also be acceptable.

Performing amputations to attach robotic limbs, on the other hand, is a completely different issue. This is a procedure that's never going to be necessary for the target's short-term well-being, especially since you cannot replace the amputated limb yourself, and even the long-term advantages are rather vague.
