Depends on what the condition is. Somebody with depression, severe anxiety, PTSD etc will harm themselves, not others....look for a way out. A narcissist, sociopath, psychopath etc will hurt others, they thrive on hurting others to make themselves feel better....as they have no conscience, no empathy, no nothing.....but each one of the conditions mentioned are mental health.....it just depends on which category you fall into My rats morbid obsession with my arm cutting was downright weird, but because of his issues, he thrived on seeing what he could reduce me to....it made him feel powerful, he knew his influence on me was strong....he had control. Well, not anymore Somebody with depression etc would still have tried to stop me, but a sadist with his conditions thrived on it. They’re all nutters....no normal person could destroy an innocent as they do......their conscience would not allow it.
