I don’t think it’s ever ok to bully anyone, no matter what they’ve done. Yes, it’s true they’ve done terrible acts, but does that make them less of a human? Does that make it valid to give them back what they’ve committed in tenfold? No.
They don’t deserve being endlessly harassed and bullied by people—but what they do deserve is being properly punished by authorities according to the scale of the crimes they’ve done.
Leave the authorities to deal out justice, it’s not your job to discipline. It’s your job to report and make sure their crime is known so it can be brought to light and dealt with, not harass them till they commit suicide or their mental health is severely damaged.
That’s just as bad as harassing any other person. Humans are humans, with real feelings and their own problems, even if they’re a few fries short of a happy meal and have done some sketchy things.
I‘m not saying that I support this particular person or sasaengs in general at all, but I can’t believe it is right for people to sit back and condone such massive and hateful responses (when they’re the same people who advocate against severe hate for idols. If for idols, why not regular people? They all deserve the basic right to not be harassed).
Apologies for the long response, I simply wished to get my point across clearly and precisely.
