I think this answer is mostly right in the case of Seven and VOY.
However, on a more general societal note, this can be problematic, as two people may have different definitions of insane (for instance, challenging certain societal beliefs that aren’t necessarily actually related to sanity may falsely be construed as insanity), and as a result, a rational person is stripped of their agency. I think several conditions need to be established for what defines someone as insane. I think if at least one of these is true, it can be called insanity:
- An inclination for self-harm
- An inclination to harm others
