Isn't that person temperamentally vulnerable to mental illness? (They must be a real hardballer)

Isn't that person temperamentally vulnerable to mental illness? I think this might be a misconception held by the police.
Let me give you two specific examples.
"There is a certain member of the National Assembly in Busan who seems like a real predator, someone truly cold-blooded, but when faced with sexual assault charges, they commit suicide within three months, right?"
"There was a news report about a Deputy Commissioner in the Jeonbuk Provincial Police Agency who climbed the ranks well, but suddenly committed suicide after getting involved in a major case, right?"
They say someone was intentionally failed during an interview, driven into schizophrenia, and then followed/harassed for another 10 years?
In truth, among the women I've met in Busan, if they endured all that, there would be no survivors. Honestly, I am confident that even their parents and siblings would have zero survivors.
They aren't someone who is temperamentally weak; they must be a total hardballer. The toughest person in South Korea. For 12 years, they endured everything raw—without traveling abroad, without relying on religion, and without ever being hospitalized.
That is why, in truth, there are no survivors among you.
