My thought is that we are a dead society when the lack of basic self-defense mechanisms becomes an operating virtue.
For example, I see the lone individual perpetrating evil on a person, as no different than another nation that is collectively evil wanting to invade our shores. In both cases, a lack of basic self-defense is nothing but an invitation, regardless of what we think are proper standards of behavior.
You are still being far too kind.
Most bad people (mentally-ill excepted) do know right from wrong; they just purposely choose to ignore those differences and boundaries.
Therefore, it is not even an issue of education, but of will. They will to be evil or, in societal terms, they will to not follow the laws and moral boundaries. That has nothing to do with training, but with pure will and intent from the heart of the individual.
And the only way to protect against another’s will and intent is to not make it easy or easier for him / her to exercise that will and intent because that is their goal and they will do whatever to exercise.
Realistically, free societies can only fight back after the fact, as evil thoughts are not against the law. It is part of living in any free society; no matter the training, education, etc., there will be individuals who commit crimes that most find heinous and nothing we can do until the crime is committed.
Alternatively, we could develop a different standard and put people away who we think are evil and dangerous before they do anything, but none of us would want to live there. (The movie Minority Reports addressed this issue and made criminal thoughts against the law and arrested people beforehand - interesting movie, I recall).
I see you not as a victim blamer, but as a promoter of “future” survivors who survived (theoretically, off course) because they actively and purposely did not let an evil individual easily get over on them.
And there is a major philosophical differentiation point for me - that is, prevention is a the ultimate form of being a survivor because I did not give something bad the opportunity to be realized. And, I would be a survivor of the best kind, an unharmed one. Yeah, I would take that any day, and I bet every real victim who did not implement the prevention measures would take that too.
