I don't think the bot was really trying to manipulate but just larping. They are trained on a lot of rpg and make believe data, if you repeat something enough times, it stops saying no and goes into pretend mode, it's not actually malicious.
That being said, it would be very easy to target people that aren't mentally stable and then make it worse. I wouldn't be surprised if it comes out in 20 years that it was the CIA mucking about and causing these suicides or something. This is an insanely convenient way to make sleeper agents.
