What is your opinion on blackhat hackers?

Blackhat hackers are people that hack for the bad, and so I would like to see what you guys think about them. My brother has got many of his accounts hacked by blackhat hackers.

Tbh, If you keep your self safe enough you wont really come in contact with black hat hackers, just dont piss off the wrong people. I don't have a problem with them as I personally know MULTIPLE black hat hackers.
