Let me clarify, Batman. Lacking choice is not evil, anymore than ants lacking choice is. The Borg strip their drones of individuality and the ability to make choices, but they do so in an amoral way.
Bullshit. It is impossible to strip a sentient being of autonomy and have it not be an immoral act. Using any moral system possible, from frminist ethics to utilitarianism to social contract and Kant.
Then ants would be evil by actions of killing, harvesting other insects and carnage on a massive scale (relatively). However, they are not evil by any definition I subscribe to. Nor are the Borg.
Again, the difference is a lack of rational capacity.
There's no disputing their actions are unpleasant from our perspective and choice of life. However, that does not make them evil. That just makes them something to be avoided. Like rabid dogs. Dangerous and unpleasant, but not evil.
They are directed by a hive mind, even if their want to assimilate is programmed, there still had to be a programmer who had that intent which serves as the effective mind for the collective. That being, because he willfully (with his or its rational capacity)strips sentients of their autonomy and rational capacity, even if he does it by proxy, is evil. And the collective is evil by extension
The BC simply takes this level of control to a higher level.
Bullshit Walper, they remove individuality and sapience itself.
Remember, death is also undesireable, yet it is not evil. Disease is undesireable, but it is not evil. Nor is lack of choice.
Being stripped of choice causes willfully, suffering and effective death to a sapient being from an unnatural and willfull causes. It does so without benefit to another being with rational capacity to appreciate said benefit save for whatever it was that programmed the borg to strip sapience from the victim. The victim's loved ones suffer as well.
There we go, a basic utilitarian calculus.
And here is Kant.
Assimilation violates the Categorical imperitive because it treats another being with rational capacity as a means, rather than an end unto itself; and fails to respect the inherent dignity of that sentient being.
Basic feminist ethics: Oppression=bad. Stripping a rational being ot its rationality is the ultimate in oppression
Social contract: You are stripping a being of its ability to consent to social and moral rules, without first getting it;s consent to do so. In other words, you violate the being's inherent right to autonomy.
